The teen years mean father and son trips are a lot lamer than they were when my son was young. Not that I’m slower, or less adventurous, but I’m just not as cool as his friends are.
[as usual, click photos to enlarge.]
The solution to this, is of course, to bring friends.
Adam had been on a spring fatbikepacking trip with us, and he is good company and competent outdoors. He has many skills, and can keep both Tadhg and I interested with his memory of interesting facts. He also has his own fatbike.
This trip ended up being a bit more challenging than I originally anticipated, but with the challenge came adventure. We had some of nearly every type of snow, lots of pushing, a river to ford, and nearly a full day of blizzard conditions. And yes, we did eat a bag of chips and hummus for breakfast.
Adam may have to sleep for a week after riding, pushing, and carrying his bike on over 80km of winter trails, but I hope he’ll have memories for a lifetime. This was full-on adventure riding, and when things got tough, the kids were up to the challenge.
This is where I spotted the new bridge over the river we just forded.
My friend Guy is a super positive influence to take on bikepacking trips. He always has a new piece of home-made gear to show off, or a new idea to solve a common problem. He never whines, which is good, because…
The Sensible Part
Our first night out was led by our mutual friend Steve O’Shaughnessy, the host of the Bikepack Canada Podcast. Since Steve had to get home to his kids early, he wanted to show off his favourite camp spot within an hour of his home. Steve is very fortunate (and grateful) for the beautiful Lake Enid that sits an easy ride from his home.
In what I think of as the middle of the night, Steve was up and away at 4AM (sorry Steve, we did not get up to see you off). That left us with my speculative plan of reaching a camp spot near Dave White Cabin, about 1000m higher in the mountains. There was ice on the water in the morning where we were.
We Find Winter
Around 30km into our ride, things started to get really scenic, and also somewhat covered in snow. Just a few km later, and a couple hundred metres higher, the somewhat covered became completely covered, and the snow started getting deeper. We hadn’t brought fatbikes, who does for unknown conditions high in the mountains in late fall?
We got to some steep, rocky, snow-covered trail, we pushed the bikes onward. Guy didn’t whine, in fact, he seemed happy, just like I was. We didn’t make it to the cabin, we did make it to some nice larches showing their beautiful golden fall colour. The mountains were stunning. Don’t go, you’ll hate it. We set up camp early enough to eat in the last of our natural light.
We had first tracks except for this guy.
We Sleep Through a Cold Night
The cold warning went off on my InReach at some point in the night. That usually means -18ºC, though the temperature on my thermometer was -14 when I got up after sunrise. I am very glad that both of us were prepared, because that is definitely into the realm of cold temperatures. I usually use my jacket in its bag as a pillow and I was within a couple of degrees of swapping it into a jacket and using my clothing bag as backup pillow instead. With my -10ºC quilt, and my hacked Costco blanket, I was theoretically good to about -17ºC plus a wool sweater.
Coffee, breakfast, a ride back to Invermere filled out the rest of our winter mountain adventure.
I’m told this area is popular with snowmobilers in winter. I think we may need to go back and try our luck after a few snowmobiles have packed a trail for us. Worst case, we have fun again.
Thanks to Guy Stuart for the pictures of me and the better scenic shots, to Kimberly for the group shot, and to Guy and Steve for being the kind of friends they are.
I originally had a 4-day loop planned for this weekend, It definitely involved hot springs. Life, and drying out an iPhone that had spent some time submerged, got in the way of the 4th day, and I set out from Radium late Friday afternoon. My bike was loaded with my packraft, paddles, pfd, 4 days of food and camping gear.
A bit of highway riding got me to Settlers Road FSR and the start of the fun. A quick 15km down the low-traffic gravel road took me to my set-in point near Nipika Resort.
The Kootenay river is not as straightforward as the Bow River that Fiona and I had paddled two weeks ago. It has several challenging rapids, and the flow rate is much higher. I was not ready to paddle something like this with kids. I’m sure they could have managed, but I did not feel prepared for river safety with children without another experienced paddler.
The river did not disappoint. I paddled to the famous Horseshoe Rapids, pulled out, decided I really wanted the provincial rec site on the opposite shore, and paddled across again. I had a relaxing time eating and watching the standing waves in the river.
Saturday, after some quick boat patching,to deal with a slow leak, I hit the river again. What followed, was four more hours of rapids, canyons, cliffs, and sensational river beauty.
Biking After the River
I had a vague plan to visit Lussier Hot Springs, and ride the Lost Elephant Jumbo route back to Invermere. Being short a day, I decided to shorten the route and visit the Red Rock Hot Springs instead.
I was just rolling down to the river to cross to the hot springs when I met a couple in a Jeep (on about the most backroad of back roads) who filled me in on how the “hot” springs were only lukewarm, and covered by the river when the river was high (it was).
I re-routed myself on to the Jumbo route. I figured I’d get some riding in, and camp for the night.
Things Go South
My dehydrated dinners need water to re-hydrate. The pass I was climbing had wet forest all around me, it had hailed on me twice. All of BC has streams and creeks, and rivers, it’s kind of their thing. Unfortunately, the trail I was on had only dry creek beds. I was alternating between pushing and riding because the trees were so wet that I was getting soaked if I rode, and too sweaty if I rode with my paddling jacket. I pushed on for 2 hours without finding a creek. My GPS told me the pass summit was 4 km away, but that was up switchbacks, so it took 18km of pushing/riding.
As it got dark, I finally crossed the high point of the pass I was on and found a creek about 200m down the opposite side. I quickly put up my tarp as darkness settled in and it began to rain. I tossed my stuff under the tarp, and inflated my mattress. Unfortunately, I then put it down on a sharp stick and had to repair the puncture – and the glue wouldn’t stick to the wet mattress, and the patch wouldn’t stick. It got cold, it was raining, I was having a lot of fun.
I awoke to near 0ºC temperature, fog, but weather that looked like it was clearing. A quick coffee and some food and I was off.
After some great downhill and some wonderful singletrack (Spirit Trails? east of Columbia Lake) I dropped down on to the highway to make time back to Radium to pick up my family.
Note that this route would be entirely possible without a raft since there is an FSR that parallels the river for the entire water portion. It was my alternate route if I had found the river paddling too risky.
Life moves pretty fast. You don’t stop and look around once in a while, you could miss it
Where Can I Go Bikeraft Camping Near Calgary?
I got myself a couple of packrafts this year, and I’ve been itching to take them for a long trip. Since quick trips involving rivers are generally unidirectional, combining the rafts and bikes is a win as far as retrieving my car at the end.
The Bow River in Banff National Park offers enough current to keep things interesting, and a highway that Parks Canada claim is a cycle-friendly route to reach a put-in point. Add to that, just a few km down the river from the Castle Junction put-in point is a a water-access-only backcountry campground where we could book a spot.
Two Packrafts Means I Need to Bring a Friend
We aren’t quite ready to leave the kids behind for a weekend, so we generally split into parent/kid pairs, or go as a family. Fiona is usually my best bet for adventures, she loves to sleep outside and try new things. She also has been really keen on the packrafts in general and has been out on the Elbow River near our house a few times. So it was that Fiona signed up for this trip. I booked the site on Friday afternoon.
We drove out to Banff Saturday afternoon, got the bikes out of the van, and hit the road. The Banff Parkway is less-bike hostile than the Trans-Canada highway, but it has narrow shoulders and enough rental RVs on it to make it scary, even if the speeds are low by car standards. Even if 98% of people give you lots of space to pass, that leaves you with some near misses on a ride like this.
With a long break at the Johnston Canyon trailhead, we got to Castle Junction and put in by 7:45. I knew the paddle wouldn’t be long, there was a good chance to see wildlife in the evenings, and the sun doesn’t set until after 10pm, so I wasn’t in a hurry.
The paddling did not disappoint. We saw a herd of elk, and many cool waterfowl. The current was fast, and there were many rifles and waves to keep things interesting. Fiona was pretty good at spotting the sweepers that were waiting for us on every bend. One bend had a herd of elk. We also saw many different types of waterfowl.
Our burrito dinner was its usual delicious, and after some reading, we settled down to sleep.
We learned an important lesson in the morning about inflating rafts, the bikes need to be removed, unless you really like the inflation by mouth part, in which case, if you leave them on you’ll get lots of it. Turning the boat upside down so the bike is at the bottom seems like it would work, but the inflation valve is then under the boat. I did have some good luck with propping the bike up with stuff.
The second day’s paddling featured the rapids at the Redearth Creek Junction. We pulled into a large eddy to scout the rapids. I was pretty confident that Fiona could handle them, and so we opted to paddle them rather than take the portage.
Fiona loved them. I was a little tense as I followed closely, prepared to rescue if needed, but Fiona navigated well, and the water was high enough to cover most of the rocks that might be a hazard at lower levels. The boats handled quite well. I had installed spray decks on them in anticipation of the rapids. Even without skirts, the decks prevented the waves from filling up the boats and making them handle like, well, like they were full of water!
For future trips, I might try for an earlier takeout point since getting to the bridge required getting through a long stretch with almost no current. Packrafts are not ideal at covering distance on flatwater. Fiona was not happy about how tired her arms were for the “very boring” flat segment. Either way, we both had a great time.
Bike specific clothing is often not suitable for all types of bikepacking. After 4 days of riding, padded shorts lose their appeal as they gain in olfactory impact. I like to wear fairly normal clothes, but they don’t always hold up to the biking or to the cold.
I find when riding bikes in the winter, the fronts of my legs get colder than the backs. There have been commercial tights that address this for cross country skiing, but they often lack the taper cuffs that work best for bikes. I also find that most tights fall down when I am riding bikes. I made my tights from windproof fleece in front, and a stretch fleece in the rear. I had initially planned an elastic waist, but decided I would be much better off with suspenders. The suspenders keep my tights from falling down and thus prevent the fabric from snagging on the seat and causing hilarious crashes.
Winter cycling jackets are similar in that a windproof front and breathable back is ideal. Jackets are not as easy to sew as some of the other items, but they are still within reach of most people’s skills. Fiona has what I think is a nearly ideal bike jacket in that the front panel is windproof fleece, while the arms and back are a breathable fleece. This keeps the vital organs warm while airflow to keep dry and not overheat. For cycling, I always cut jackets a little longer in the back and put longer arms on them than on a standard jacket to compensate for the cycling position.
“Don’t forget to mention your mom”
My mom loves to knit. A few years ago, she knit me a pair of socks. She wasn’t sure I would like them, and she was pretty sure that they weren’t as good as the commercial socks that I buy.
It turned out that the socks my mom knits are warmer, fit better, and last longer than any socks I have purchased. So if you knit, or know someone who is kind enough to knit you some socks from Merino wool. (lately my favourites are a Merino/Silk blend) I strongly endorse home made socks.
I have several store-bough hats that do most of what I want. I am fully happy with them as my day time headwear. For sleeping though, I want something to replicate the hood on my mummy bag when I use the quilt, or even just to supplement the mummy bag hood.
Jeremy and I had not gotten out for a bikepacking overnight since the weather turned winter. I planned to take my family, and invited Jeremy and some other friends to add to the fun.
The Actual Group
By the time Saturday rolled around, it was Jeremy and I and a daugher each. Jeremy’s daughter had been with us before on rides, but this would be her first bikepacking ride on snow. We hoped for a firm or firmish trail.
My family are equipped with fatbikes and winter camping gear. Jeremy’s daughter is still on the small side for a 26″ wheeled mountain bike, so she was on her 24plus bike, she weighs little enough that the tire pressures can be run at roughly what an adult fatbike can. Jeremy is a fatbikepacking veteran, so he has more than adequate gear. He brought his own -32ºC Western Mountaineering sleeping bag for his daughter to ensure that she would be warm while they slept. Their tent was pretty much filled with down insulating products.
The only gear that wasn’t quite up to the task were a pair of Bogs boots. These boots really should come with a warning label. There is way too much thermal mass in a Bogs boot to consider it a viable boot for any kind of long-duration winter activity. There were tears Sunday morning as the frozen boots sucked the life from a young girl’s feet. Thankfully, the sun eventually came over the top of the mountain, and we put the boots in the sun to warm. My new official policy on Bogs is that they should be restricted to the wet season, as they are truly great for keeping feet warm in cold (liquid) wet conditions.
As dads, our job is to help our girls to prepare for life. A bit of challenge and a lot of fun meant that this trip helped the girls get a little extra empowerment, and some of the bragging rights that come from doing something a little beyond what the average kid has a chance to.
The trail was firm enough to ride, but soft enough for a bit of challenge for the snow-bike rookie. Fires are permitted at the SP6 campground, so our burritos were roasted and yummy. The temperature dipped down to something below -18•C at night, so we were glad we brought appropriate sleeping gear. The stars were bright, and we all slept well. The dads did not get their fair share of chips, which was my fault since I neglected to bring a bag of my own like I usually do.
The girls agreed that they were glad they had come, and that’s really what counts.
Many of these photos were courtesy of Jeremy, thanks for helping me get outside.
I have been lamenting the lack of a winter ultra race in the Calgary area for many years. We have a great location for it, all we lack are enough connected winter trails that together could make an exceedingly difficult race. One where if things weren’t ideal, walkers and skiiers would keep up to or pass the folks on bikes. One where some years no one would finish. I also wanted something scenic that most people would not otherwise experience, something that would be a rewarding tour.
Pick a Route, Any Route
I decided to put together a route, any route, where I had ridden most of it in the past. My prime criteria were: it had to pass mostly through areas where random camping is permitted. It had to be difficult to complete in 3 days, and bikes needed to be permitted on the trails.
Once I had something mapped, I thought I’d do a weekend test ride on as much of it as I could possibly do. I was pretty certain adding the Highwood Pass section of closed highway would be too much for me, but I did want it to be difficult.
Winter ultra races like the ITI have always discouraged comparisons between years as invalid since conditions have so much effect on a race. Often, a lead racer will be caught by the rest of the racers when a storm holds them up. Sometimes, an hour’s worth of snow accumulation means the lead racer can open an hour’s lead to days. Some years, a route is impossible.
A 3 Day Tour
I left Friday morning, to start a 3 day full-speed tour. I knew conditions were to be cold. That can be a good thing, so I wasn’t worried. I was concerned about the snow, but I had hopes that someone would have snowshoe packed the first bit of trails, and that snowmobiles would have passed on some more of the trails, and that I could push through the rest.
The “Short Loop” of Prairie Creek and Powderface Creek is one that I’ve done dozens of times, it sees consistent snowshoe traffic and so is generally pretty good. Indeed it started reasonably, having been snowshoed by at least a few people. It was mostly rideable, if a little soft and slow. The trouble started when I turned up the trail to Powderface Ridge. It had only one set of touring ski tracks, and they were not hard enough to ride on, nor to walk on. On top of that, some wild horses had used the trail to move between grazing areas leaving some sections of trail pocked with deep footprints. My progress slowed. I was moving at about 1km/2hr, this was the kind of challenge I dreaded and wanted.
With a race roster, the second through last racers get the benefit of trail breaking by the lead racer, in my case, there was only me. I’m pretty fine with pain and suffering though, so I continued on at a ridiculously slow pace. I moved my gear to a sled that I brought to pull the bike in, the depth of the trail meant the bike dragged on the trail sides, so it was just the gear. Still, the lighter bike was easier to manage.
Then Things Got Worse
As the sunset approached, I started feeling a little chilly. First I had to put on a sweater. At this level of output, it is rare indeed to need much in the way of torso clothing. I checked my thermometer and saw that it was indeed below -30ºC. I was well prepared though, so I didn’t really worry.
The trail didn’t get any better, but there were some more substantial uphill bits, which slowed my progress even further.
As the temperature dropped further, I decided to sleep before I was out of the trees on the exposed side of the trail. My estimating from the bottom of the thermometer scale to the line on the thermometer put the temperature somewhere near -38ºC. That’s into the realm of cold, even for me. Frostbite from touching metal is within seconds, so everything has to be done with mittens on. Even lighting my stove was a challenge, as the white gas fuel needs a flame to it for a couple seconds before igniting.
A Good Night’s Sleep Always Helps
I wasn’t racing, but I was tired from the effort. I slept soundly from about 10:30 until 7AM. When I woke up, it was near enough -40º. Making coffee was tricky, everything wanted to freeze, I don’t think the makers of Aeropress intended it to be used at -40º. I had to use my hot water to thaw it to open it, then I used more hot water to warm it, then I had to quickly make the coffee before it froze again, and yet, my coffee was very satisfying.
Now, the logical choice when faced with such an obstacle as this trail, is to turn around and go the way that you know will be easier. For some, this would be the fun way. Instead, I wanted to stay on my intended route. There is a great deal of satisfaction to be gained from doing something hard.
Packing up is never my strong suite, but packing gear in -40º is a real challenge. Taking mittens off for even a few seconds is uncomfortable, not just while they are off, but because when they go back on, they have cooled enough to be painful to touch. Either way, I got myself packed and underway.
And Then Things Went South.
I knew by this point I wasn’t making it the full distance. I was fine with that, because I was in the backcountry, in the cold, and well away from my comfort zone.
The 2.5 hours for the remaining km to the saddle at the top of this section of trail was not that onerous. I was feeling good after a nice night’s sleep, and I was in a good frame of mind (though a horrid song was stuck in my head). I reached the top and decided to send Tania a reassuring message about not worrying that I was so slow, when I discovered my InReach Mini was missing. I ordinarily have it mounted on my bars with a carabiner to secure it to something in case it falls or breaks off the mount. But, the InReach Mini is only rated to -20ºC at which point it starts to turn itself off, so in the cold I had to put it in my pocket. One of the times that I put it in the pocket, I must have failed to zipper it in (it was -35º, I was wearing mittens).
The InReach Mini is an amazing piece of technology. It allows me to reassure my family that I am okay, it lets me call for help in an emergency, in short, it is a great communication device for the backcountry. It is also very small, and pretty much impossible to find when it’s dropped in the snow. I had no choice but to stop my trip, go home where I could retrieve the last position the InReach sent, and to go back to try to find it another day. I was devastated. I had not had a solo winter trip in years, and here it was cut short by my carelessness.
The Consolation Prize
When I got home, I looked up the track from the InReach and it had sent a final location. Fortunately I had had tracking turned on. After driving back and skiing up to the place where my GPS showed the device should be, I started raking the snow with my ski pole. Less than a minute later, a little orange device popped out from under the snow on the trail. I was thrilled, both at not having to replace it, and that it was so accurate that I could locate it within a ski-pole’s length.
I was prepared for comfort at -40º
Tether the indispensable electronic device (if you have to move it from its correct spot)
I don’t mind when things are tough, but I don’t like when I mess things up myself.
My previous philosophy of no sled with the bike was mostly correct.
Count calories: I know how much food I can eat, and I brought too much of it.
In the end, you’ve got no one but yourself to blame.
km travelled: 13 of 178
Hours moving: 12
Hours sleeping: 10
Hours searching for device: 3, with a 5 hour trip the following day
The Gear That Worked:
My sleep system as always was a -10ºC down sleeping bag with a home-made -10ºC synthetic quilt over it. My sleep system is a Thermarest Ridge-Rest with a Neo-Air Xtherm over top. I was comfy at -40º, my only complaint was that it was hard to see the stars with my sleeping hood done up. I brought my tarp but did not use it.
My bike is my usual Salsa Mukluk Ti with a Rohloff hub. I was pleasantly surprised that the Rohloff shifted well at -35ºC.
My bike luggage was my usual Porcelain Rocket bags with a custom spacer for the bar bag from Tadhg.
Pogies were my own design, they were warm enough but I really should have insulated my brake levers as I have done on my kids’ bikes.
As I read this I realize that I have not put the most positive spin on it. While this was not a successful trip, it was a trip, and I didn’t see anyone else out there, so that’s something. Also, while I did mess up my weekend, I can honestly say that I lived it, rather than wasted it.
Back in the 90s I started riding my bike to work after a hiatus of a few years. My coworkers would regularly ask me if I was going to be like Tom, a notoriously all-weather rider. As winter came on, I realized what most people who cycle in the winter do, it isn’t as hard as it looks. It can, however, be cold. With the internet in its infancy, it wasn’t easy to find quality information on how to stay warm in winter, but I knew at the time that my airways were a weak point in that I couldn’t really insulate them from the cold air that passed over them. Then I read about a product called LungPlus and my obsession began.
The Untold Story
The human body is remarkably good at keeping itself heated. The circulatory system will gradually move blood flow away from the surface and away from extremities to keep its vital organs warm. Activity, including shivering, will help by generating heat. But in order to do any sort of activity, one needs to breathe, and in the cold, that means breathing cold air.
The air passages are designed to warm up air as it enters the body so that the blood can pick up oxygen from it. Unfortunately, this is exactly the same as wind chill. On top of that, the airways are damp, which means they are subject to evaporative cooling just the same as if a person was to go outside still damp after a shower. Except that the lungs have approximately 5 times the surface area of skin, and they are always naked.
Well, What the Heck am I Supposed to do About it?
If you stop breathing you will die.
The simplest form of heat retention is the extended hood that Northern peoples have used for millennia. It creates a pocket of warm air around the person’s face, and helps take the edge off breathing in extremely cold air. In turn, this pocket of warm air requires less warming by the airways and lungs and so is pulling less heat from the body.
The next low-tech solution is the scarf, Buff, mask, or bandana across the face. These do capture some heat from the outgoing breath to warm the incoming air, but their primary purpose is to warm the face itself. They are great for preventing frostbite on the face, but they do relatively little to prevent heat loss through breathing.
The next technological step is to use a heat retention or heat exchange device to capture the heat from outgoing air and return it to the incoming air, and that is what this article is about.
Yes, 6 Heat Exchanger Masks.
What follows is a brief description and mini-review of the 6 heat exchanger devices that I personally own. Yes, I could have gotten away without buying more of them, but in my efforts to optimize, I have continued to purchase more.
This device is the only one on this list that does not have a mask with it. It was the first one that I used back in ’99 or ’00. The device is a bit like the mouthpiece of a snorkel with a heat exchanger built in to it. It isn’t fashionable, or really even dignified, but it does work.
It helps keep glasses unfogged by routing breath away from the eyes.
It is an effective heat exchanger and helps to keep the body warm
it routes the captured water away from my chin and reduces beardcicles.
Looks like a science fiction device worn by Venutians to breathe the earth’s poisonous oxygen.
It routes air through the mouth and I find it sometimes makes my teeth cooler
droolcicles at the end
Oh yeah, this device lets you breath warmer-than-room temperature air. Oh damn, when I exercise it is like breathing through a straw. This is the best device for waiting for the bus.
This device is great, if they still made them, I’d have bought more.
great heat exchanger
close fit to the face
low profile balaclava works well with other hats
very free breathing and the air path does not ice up
the exchanger sits close to the lips and can contribute to chapped lips
the exchanger forms a shelf that can collect snot
they were bought by another company and were discontinued
This unit is a little more sophisticated than a long hood on a parka, but not much.
Simple, never clogs
keeps the mouth and nose clear so skin stays un-chapped.
no real heat exchange, only a pocket of exhaled breath at the mouth
some (Tadhg) find it restricts breathing
I bought this one based on a review from a friend with more cold weather experience than me (yes, those people exist).
Very effective heat exchanger
good airflow for high-output activity
keeps wet parts off the face
the “Darth Vader” look
does eventually get somewhat wet
the “Darth Vader” look
the great balaclava is a bit tight on my enormous head
This and the Ergodyne are my go-to masks for cooler days. Back to back testing today gives the edge to the AirTrim for warmth.
doesn’t restrict breathing
away from the mouth and nose for reduced chapping
doesn’t put pressure on the nose – less runny nose
is available with a selection of exchangers with greater flow, or warmer air depending on activity
Recently, a grade 2 kid said it looked like a pig nose
it does not cover the upper cheeks – risk of frostbite
if you neglect to blow the water out of it the water can drip on clothing
Finally a recommendation
On the bike, and this is at least partly a blog about bikes, the Ergodydne has the edge because of its coverage of the cheeks. However, if you have or can get a face mask that covers the cheeks and leaves the mouth and nose free, the AirTrim’s superior performance will win out. All this week, I was outside in temperatures as low as -29ºC with the AirTrim on, and I dressed exactly the same as I would have for -12ºC without the AirTrim (yes, it is that good). I don’t get a commission, though if the good folks at AirTrim were to send me 3 more for the rest of my family, I’d be mighty grateful (hint, hint). I bought my AirTrim from skiwax.ca
If anyone thinks I am exaggerating the benefit to these masks, they should head on over to https://thismombikes.net/ to ask her how inadequately she has seen me dressed in this cold snap. Below -25ºC roughly 90% of a body’s heat is lost through respiration. if you could reduce even 15% of that it would be equivalent to doubling your clothes. When you keep your core warmer, it signals the brain to send more blood to your extremities, so in a way, the heat exchanger mask is a handwarmer too. Not that I want to discourage you from buying a pair of the pogies I make by hand.
What About Medical Benefits?
We’ve all heard about the dangers to lungs and airways of breathing extremely cold air. I am not a physician, nor do I play one on TV. I am way too lazy to do the research as to what medical benefits these masks may give to users. Even if it were no medical benefit, I would still use one for comfort and for warmth. Airtrim and Lungplus have some medical articles on their sites that I have not read.
Lungplus sent me free product in about 2000 with no conditions attached. I have purchased all the other products myself with my money. At the time I am writing this, I derive no benefit from sales of any of these devices. I have received no money for this review, but I won’t turn down offers of free product.
