Little tip concerning hot hands: I use them to keep my electronic devices and water filter warm when I winter camp. You won’t wake up to all your batteries drained and your filter frozen and compromised. Bring a bubble wrap envelope (from an amazon delivery) toss anything you want to protect in there, then throw in a hot hands, leaving it open just enough it gets oxygen. Come morning time you can continue to use it in that manner, or take your stuff out, seal the envelope, and the hand warmer should deactivate and will be usable the next night too

Smart! I've been thinking about making a envelope out of reflectix for this same thing, minus the hot hands. I was thinking the reflectix might be insulative enough to keep the items inside from freezing but idk. Might have to test it out this winter.

@@MidnightLight. I can’t say it could never happen, but I can say it’s never happened in the number of times I’ve done it. Never seemed to get close either. Bubble wrap isn’t THAT good of an insulator, and if you’ve got it wrapped up tight enough to really hold in heat it’s likely starving the heater of oxygen and slowing down the chemical reaction too.

I like to put one of those silver mylar emergency blankets between the tent floor and my pad. It act as a bit of a radiant barrier to keep thermal migration down.

Pleeeeeeease put the down beanie on, please. 🙏🏼 There is absolutely nothing to smile about in the UK right now! 😢

I have tried 4 different liners and they all sucked and didn't add any warmth or feel comfortable... then I decided to try Appalachian Gear Company's alpaca liner and wow. It is so warm, comfy, and it doesn't get twisted up when I toss and turn! Love that thing.

Alpaca is crazy warm

The sleeping bag liner really is a game changer. My first time using one was about 6000 ft up Mt Rainier in February a couple years ago. My bag was rated for 20F , the liner rated for another 25F. It got down to right about 0F that night. I started the night off a little cold, but by midnight I had stripped off every bit of clothing in an attempt to stop sweating! 😅

Sweating likely came from creating a situation where your bag could expel your body moisture because it was suffocated by the inner bag. It could not breath. Which creates a whole host of other problems like moisture build up from adding layers of nylon and insulation that were not part of the testing or design process that went into rating the bag in the first place.

@@kookiemoose moisture build up is kind f ow this keeps you warm. Water evaporating uses a lot of energy. By keeping the vapor inside the liner, you prevent more water from evaporating and get back some warmth from the condensation process.

Honestly, I find that an overlayer or bivy sac or both is better than a liner. Leaving more room in the bag. A stitched envelope of a wool or polyester blanket works great. And it keeps your sleeping bag protected from the elements.

I always said. I don’t care what I look like, just that you’re warm. Remember when the first time winter hiking camping. Years ago. Love the videos.

I have a pair of down booties and I always bring them in cold weather to sleep in for both my tent and hammock setup. One of those things I am glad I learned about them. I also bring a few hot hands warmers. I use them usually for a heat source at night if I get cold sleeping. Mini heater to take the edge off. Great video!

Where do you put the hot hands when you are in your tent

I bought down booties last year but was too warm to use them. Use them for the first time this past weekend and that combined with a warmer sleeping bag made me wake with a start because I was so warm and snuggly that I thought I was in my own bed :p

You should do a video on what to pack when you're hiking in mountain ranges that create their own weather. Rainier, Mazatzal. These places are some of the hardest to prep for without taking everything. Forecast of 70 and sunny and getting 30 super rain cell and 50mph winds

Just started getting in to backpacking along with my years of WV Native Trout fishing. Your videos have been a real help. Thank you.

My favorite is when I’m prepared for a blizzard and the forecast was horribly wrong 😂

Appalachian Gear's alpaca wool sleeping bag liner and their hoodies are my absolute favorite cold weather backpacking gear! So incredibly warm and cozy. Loved all your tips! Thank you so much for sharing.

Can confirm that down jacket is awesome....bought it on your recommendation and take it on every trip!

I have to say, I do really like your videos. They are lighthearted, honest, very helpful and they don't push the typical "you have to have this high-end high dollar gear" that so many other youtubers push. You give examples and your opinion through your experience and let the viewer decide for themselves.

Good suggestions, Dan. I bought a new synthetic fill sleeping bag specifically for mountain snow conditions that includes a built-in vapor barrier liner (total weight 4-3/4 lbs). It works very well in temperatures under 20-degrees F, especially at 0 and below, anything above 20 degrees and the bag is too warm and sweaty.

Great tips, Dan. I always struggled finding stuff to stay warm without overheating.

The Western Mountaineering booties are amazing. I was toasty in 15 degrees and the ability to wear them outside for nighttime visits was very important!

Dan snuggles up with Emmitt to keep him warm LOL 😆 How sweet!

Planning on hitting the New England trails this January once I've got all the gear I need... Thank you for posting this! Definitely getting myself some booties and a flextail!

Thanks Dan for the late video, I was freezing my tuchas off in Santa Fe over the weekend AND THEN you drop this video telling me what I shoulda done

those hand warmers saved my life when i did my very first snow backpacking. totally unprepared for the cold, luckily i brought a bag of hand warmers and used it to heat inside my tent.

Love the videos Dan. I am not an avid hiker but I like camping and keeping it light. I always find something useful in your videos. This one… inflate your mattress outside. It just makes sense. Thanks man.

What I am interested in trying out, is my cooler box as a heat insulator. Putting some thermoses with hot beverages inside, so I can enjoy some warmth before freeing the car for the return trip. The inside is covered with heat reflecting material, and I got the useful tips of turning it upside down and leaving the box on one of the seats and cover it with a blanket to minimise heat loss.

Since the last 3 weeks of my hike unexpectedly turned into a winter hike (temps in the teens Fahrenheit, fully frozen waterbottles in vestibule in the morning), and I only had 3-season gear, here‘s s few more tips that really worked well for me: - get a cozy for your gas can. it is absolutely essential to be able to boil water - make sure you bring enough fuel - I already have a synthetic puffy that I also wear while hiking. For the night I added a down vest. - have your dinners in a ziplock and an empty and clean dehydrated meal packet. when you reach camp, pour the boiling water in, stick it under your shirt, and set up your camp. eat after you snuggled into the sleeping bag. - have a nalgene bottle with you, bonus points if you also made a cozy for it. fill it with hot water and take it into your sleeping bag. reheat during the night if necessary. this also has the advantage that you actually have non-frozen water to drink in the morning. I usually warm it up in the morning, stick it under the shirt, break camp and start hiking. - obviously take all electronics and the filter into your sleeping bag. - if you‘re using trailrunners and normal socks through snow, use oven bags over the socks to make them waterproof. they last for several days without getting any holes.

I take that outdoor research beanie on every hike, even in the summer. Can’t tell you the number of times the weather has turned and I throw that on under my rain jacket. Everyone in my group starts by making fun of how ugly it is, by the end that are always asking where to get one. Once got caught in an unseasonal summer snowstorm on a newzealand volcano.. that beanie and overmitts saved me. Regarding the down socks. I have some really light weight shoe covers that I layer over the down socks as camp-ware; I do this instead of camp shoes in alpine regions. When I get in the tent I strip the shoe covers.

I would like to add something to the Western Mountaineering Hot Sac that Dan didnt mention. Its main purpose is not to add warmth to your sleeping setup but to stop your sweat from getting into the sleeping bag which is essential for keeping a down bag nice and warm on longer winter hikes. You could also try and dry it throughout the day, but that probably wont work very well without sunshine. Also i have not personally tested it but i have heard that it isnt as sweaty as you might believe.

You failed to mention that the 'Vapour Liner' for the sleeping bag also prevents your body moisture from going into the bag's loft, and reducing its effectiveness. For camping at -25C, mine worked quite well. I made it out of a Tyvek coverall, and lined it with Silvered Onionskin. Worked lovely!

First thing I thought was down booties. They’re awesome! The cheap ones work well, worth it if you get cold toes Also love tiny pump, I use it for pool toys too, what a great little device

I bought a -20F rated sleeping bag from REI in the late 70s or early, very early 80s. Still have it, still trust it. Spent a week on the shore of Lake Superior at Split Rock Light House for xmas one year. Awesome.

Excellent content as always. I am with ya, I have bought so much gear to get to where I am with a comfortable set I am happy with.

Food for thought: Sierra Madre Hot Pocket stuff sac. I purchased it and looking forward to using it this winter. My wife has already been using it while watching TV.

Very good video for beginners. Obviously, everyone is different when it comes to what they need to stay warm. I've been almost exclusively winter camping for the past decade, and I use some of the gear listed here, but I am a Yeti, so I would not need as much gear as a lot of other people. This makes it hard for me to recommend gear to beginner winter campers, so I'll refer them to this video next time, and to your channel

I have the hot sac and use it I've been in my unders in the 20s and still was sweating in it. Really good item.

20 + year user here of the Forty Below overboots. Great if you don't want to spend the money for high tech and warm mountaineering boots or if it's not cold enough during the day for warm boots. If you have the money and it's cold enough to walk with them, nothing beats a warm mountaineering double boot. The ability to remove the boot liner and to bring it in your sleeping bag can be a necessity, depends how high/far/long you go.. Fill your water bottle with boiling water, put it in your down parka/sleeping bag to keep you warm. Winter tent (no screen), candle lantern and more than one person per tent.

Slurp modulation…now that’s cool. 😎😎

Some great advice there! excellent stuff. We try to put grass or foliage (or hay) under the tent. Not sure whether it actually helps.

Great video! The Hot Sac Vapor Barrier Liner sounds great for an emergency when you don't have a sleeping bag, but I wouldn't use it in a sleeping bag because sweating in the winter is not good. Decades ago I used a space blanket reflective barrier because my sleeping bag wasn't nearly warm enough, but it retained all the moisture.

@rudysal1429

Жыл бұрын

You are supposed to use the space blanket on the outside of your bag in that situation. You don't want the space blankets really touching you because they reflect radiant heat but isn't enough of a barrier to use as a regular blanket as it doesn't really insulate in that way.

@ThatFlowState

Retaining all the moisture is exactly why one uses a VBL in the first place. The problem in very cold conditions is that your sweat (and you always sweat a little bit) can freeze within the insulation of your sleeping bag. Over multiple days and especially if you compress your bag every day this can lead to a significant loss of loft and thus insulation. A VBL prevents that by keeping the moisture from entering the sleeping bag.

It's just that you'd be making your whole bag wet instead of the VAPOR barrier.... Plus if in extreme cold and warmth is the goal..... I would almost be willing to bet you'd be warmer with the mylar next to you radiating all your heat back then being insulated by the sleeping bag

I usually go bare, but sometimes wear really lightweight polypropylene to migrate and evaporate the sweat.

There are some interesting articles about using vapor barrier sleeping bag liners and vbl clothing for winter. It'll be interesting to see if that liner works for you. Edit: When you get out of that hotsack vbl is when you freeze because you are likely a bit damp, and if you have clothes on, 😩 they are also damp and can then freeze nice and crispy when you get up. I think I'd go with vbl clothing worn under whatever sleep clothes, including a puffy jacket and hood or balaclava, then when you get out of your sleeping bag or quilt, you still have some dry insulation on because the vbl clothes keeps the moisture underneath your insulation layers. VBL's are also supposed to make you notice if you start sweating so you can adjust your layers accordingly.

VB clothing and liners can be tricky but using VB top and bottom in cold weather sleeping situations is one of the best places to start, especially if you do multi-day trips and use down insulation. I find it tricky to use when hiking as I sweat profusely without VB but sleeping is great. Nice when nature calls too as it wind-proofs your sleeping clothes substantially.

I live in Alaska and I backpack and camp all year around. The OR down beanie is the bomb. I also use a Smartwool balaklava face mask while I sleep. I put hot hand in my boots at night, put the boots in a plastic bag inside the bottom of my sleeping bag. I slept out with no heat source before -in an expedition suit at -30F. I wore mittens too. I use a big Minute Maid Lemonaide bottle to pee in overnight. What I like best about cold weather camping and backpacking is NO BEARS.

So funny. Decathlon (a french brand) is a low-cost supplier in Europe. Yes, some things are not bad. I've already checked out the down jacket. In the color shown, it costs currently €45 (US$44.50) in Germany.

I’m surprised you didn’t talk about bivy sacks. I taught backpacking, ski touring, mountaineering, and snow caving for 14 years. In the fall and winter it can increase the warmth factor of your bag and keep it dry, in a tent or in a snow cave.

Hand warmers are awesome. I use electrical tape tape one to the top of each toe, then one in each back pocket. It will keep the toes warm all night and the ones in you back pocket are where the femur artery goes through your pelvis warming the blood as it goes by. It like small electric blankets. 😎

A quick tip to get your feet warm before you go to sleep. Bounce on your toes back and forth. Turn your feet around whilst balancing on the other. To get the rest of your body warm very quickly, do jumping jacks and when you are warm enough go into your sleeping bag. I bet you will sleep very well.

I prefer a Wiggy's or Enlightened Equipment synthetic balaclava. You can hike in those and sweat without worrying about them failing, and you can breath through them without compromising the insulation.. They also compress less on the bottom of your head than down will. If you put a couple of those chem warmers near your kidneys at night, you won't have to get up to answer nature as much. Cold kidneys like to flush water to reduce the volume your core has to heat. Warm kidneys let you sleep instead.

I can see using it in a sleeping bag but I don't see how it would warm a hammock adequately.

I love the Decathlon puffy jacket that I used on the PCT. But... I bought 1 size larger & it was still a bit small. Also, the men's jacket had a zipper for females. So, it was a bit awkward starting the zipper at first.

Dan, I have a clothes iron I don’t use anymore if you need one.

Nothing like snuggling up to a river rock heated by the fire. Free heat that lasts all night long. Toss one in the bottom of your bag to keep your toes toasty. Just make sure it was not directly in the fire or you will burn yourself and melt the bag. A bivvy sac is a must for cold weather camping. Especially if you are camping in a snow cave or lean to. You don't want snow outside your bag getting it wet. And never skimp on ground covers.

The first time i ever went backpacking it got down to -10 degrees celcius during the night

Rather than the Vapor Barrier, I use a SOL bivy over my sleeping bag. It's waterproof and windproof, but BREATHABLE.
