How to Sleep Warm While Camping || REI


– Hey, Guys, what’s up? I’m Miranda from REI. Sleeping bag temperature
ratings are a great way to get an apples-to-apples comparison of different sleeping bags, but what do these numbers mean
and how do we arrive at them? Let’s talk about ISO standardized testing and how sleeping bags
are tested and graded. (jazzy bass beat music) When you’re looking at sleeping bags, you’ll often see an
ISO temperature rating. What this means is that
the bag manufacturer has paid for the International
Standards Organization, or ISO, to test the sleeping bag. This test is conducted in a
temperature-controlled room with a test dummy that’s
covered in heat sensors, and this test dummy is
wearing a base layer top, base layer bottom, as
well as a hat and socks. They’re testing it on a
winter-weight sleeping pad. The sleeping pad, as well as the apparel the test dummy’s wearing, and
the temperature in the room, is standardized for all ISO testing. After these tests are finished, ISO comes up with two different numbers. The first one, or the higher number, is the ISO comfort rating. This number is the lowest
temperature at which the average cold sleeper will
be comfortable in the bag. The second number, or the lower number, is the lowest temperature at
which the average warm sleeper will be comfortable in the bag. You’ll often see these referred to as the women’s temperature rating for the warmer temperature, and
the men’s temperature rating for the colder temperate. This is just because women, in general, will sleep colder than men. One thing to keep in mind is
that a women’s bag that’s rated for 15 degrees is going
to be slightly heavier than a men’s bag that’s
rated for 15 degrees, and this is just because the
difference in how women sleep, and also because that women’s bag is using the comfort rating,
whereas the men’s bag is using that lower limit
rating from the ISO testing. If you are a cold sleeper,
you might be inclined to go with a women’s bag
regardless of your gender identity, but keep your body type in mind, as the bags also have
different construction, and empty spaces within the bag or spaces that are too tight, are also going to affect how warm it is. While the ISO standardization is great, there are some limitations to the test. First thing is that they do use a winter-weight sleeping pad. Something like this one,
which has an R-value of 5.7. You may not use something like this, you might use something more like this, which has an R-value of 2. So, keep that in mind when you’re looking at the temperature ratings,
as your sleeping pad does make a huge difference in the warmth of your sleeping bag. The other thing is that you
might be sleeping in base layers that are warmer or not
as warm as the test dummy in the ISO test. If you’re sleeping in your skivvies, you’re definitely not gonna be
as warm in your sleeping bag as they are when you’re
there testing the bags. Another thing is that not
all manufacturers are going to pay for the ISO
testing, so you might see, on some casual sleeping bags, that they don’t have an
ISO temperature rating, just because they’re not
necessarily predicting that people are going to use
that bag in extreme conditions. Speaking of extremes, if
you are looking for a bag for extreme cold,
unfortunately, ISO testing doesn’t test bags that
are below zero degrees, so, again, keep that in
mind when you’re shopping for your sleeping bags. The last thing is that
while the ISO standards are good for averages, the
temperature that you are in your bag is going to
vary greatly depending on whether you’re a warm or cold sleeper, or if you’ve eaten a lot of
food, or haven’t eaten enough. Again, these are just there
to give you a good idea of how the temperatures on the bags work. That’s it for how ISO standardization and sleeping bag temperature ratings work. If you want more information on this, or if you’re looking
for how to sleep better and sleep warmer, I made an
entire other video on that, you can check that out as well. Of course, it’s a good
idea to come in and look at sleeping bags, test them
out, take ’em for a trial nap. Come into your local REI
and talk to the experts or test out bags there. See ya later.

  1. I know that you know this, but don't breath inside of your sleeping bag. Or rather don't exhale inside of the sleeping bag. It will ad moisture to the air inside the bag, and make you colder.

  2. Along with their tips I went camping and temperatures of 11 degrees and at night it was 7°. What helps me tremendously was taking a hot rock from the fire pit obviously let it cool down to touch and put that in your sleeping bag. I spent most of the night with the bag unzipped because it did so well. Another tip is down booties.

  3. I don't like liners, maybe due to how I sleep(moving a lot), I have a sea to summit toaster fleece, I'm all wrapped up in it (in a bad way) after a cpl of hrs. I have finally found the perfect replacement, down Booties, pants, jacket and if need be mittens,all light and comfortable. 0 deg down bag, thermarest solar and xtherm. The bottle would drive me nuts.hand warmers, much better.

  4. Yes adding closed cell foam works, but reflectix is at least as effective when used as a layer under your pad, and is a small fraction of the weight and packing space used by a foam pad. The down side is that it will be a bit noisy if you move around much in your sleep.

  5. Most definitely agree on the hot water bottle. I'll never use Nalgene bottles in the summer because they are too heavy and bulky, but in the winter I always take one for exactly this reason. And I can confirm that they will stay warm til morning if your sleeping bag and pad are properly rated for the nightly low temp. It's also a great hack because it takes MUCH less time to boil water for coffee and breakfast in the morning when you're not starting with water that's been out all night and is near freezing or frozen.

  6. Pro tip: if you are still cold, resist throwing on every piece of clothing you brought with you. The goal is to warm the air inside your bag. If you put a rain jacket or big puffy on, you will likely be colder. Instead toss the puffy down by your toes to reduce the air volume.

  7. I went camping for the first time in Scotland last summer with no experience whatsoever. Im from a tropical country so i only had a thin sleeping bag. The outdoor shop i rented my tent from gave me the sleeping pad (the foam type) mainly because I said i only have my sleeping bag with me. It works although at night what really helped was the Nalgene hot water bottle. Allowed me to go to sleep for a good few hours before i got woken up because it was freezing and the hot water has cooled down. But those few hours of toasty feet was the best!!

  8. 1- Save 2.4 oz with old school nalgene hdpe 32 oz bottle. 2- use puffy in bag/quilt as a blanket over torso, not wearing as coat is less restrictive, & more efficient use of puffy like a mini- quiltin bag/quilt.

  9. The idea of a having a snack and a warm drink before sleeping makes sense but I brush my teeth before sleeping. So I would definitely have to be out of my tent to brush and rinse and then get back in, which is doable. One thing you might have mentioned is peeing, and specifically for gals and guys. Guys can deal with that with a designated pee bottle. Women can go in the tent too, as I understand it, but the process is more complicated. I bring this up because it's super important to deal with this so the urge to go doesn't keep you awake unnecessarily.

  10. If it wasn't for people with more money than good sense this store would have been gone long ago. Overpriced crap mostly. You're just paying for the name thinking that you will look cool to all the other plastic people. Really, it just screams Dork.

  11. I like to add jello to the hot nalgine. It is light and when it cools down in the morning you can just eat the jello or drink it warm. It tastes just like cool aid!

  12. I use camp fire rocks wrap it in aluminium foil to avoid soot. rocks have thermal mass and last all night slowly releasing heat.

  13. Cut a piece of Reflectex to the shape of your body and place it inside your bag on top of you. Reflects body heat back to you and keeps me warmer than a liner and is multi purpose. Can be used as a sit pad, wind screen when cooking, rain cover, door mat for tent, and many other purposes. Weighs approx 4 oz and is lighter than bag liner at 8oz. Reflectex can be purchased at home improvement stores. This kept me toasty in windy 25 degrees temps.

    Yer aw saft shites

  15. My warm sleep secret is a 68 pound American Bulldog. I side sleep and she goes from my butt to my feet. I use a pad and a quilt and wear a long sleeve shirt,long boxers and wool socks.you will never have a cold night sleeping with your dog.

  16. Hammock crew report in. I can sleep on a 45 degree slope as long as there's trees to hang my hammock. Never worry about vacant campsites again. Make sure you have a good under-quilt though.

  17. Don’t sleep in socks or at the very least the ones you’ve been walking in all day. Damage to your feet is no good

  18. I always use the 2ft by 6ft inflatable pool floats as a great sleeping pad alternative. You can take a couple of them. They're lightweight and super cheap and they're about 6 or 8 inches thick. They make awesome sleeping pads👍

  19. I would like to add to the list. If you have to go, go. If not, your body use a lot of energy to warm up your P.
    That is energy your body could have used to keep you nice and warm instead.
    Greetings from Norway.😊🏕

  20. Do y’all have any informational videos about hammock camping? If not y’all might want to look into it. Since it’s becoming very popular these days. Something else to eat instead of shortbread cookies is beef sticks. It not only kicks your metabolism up but you’re also getting the added benefit of protein, which is important.

  21. Get that liner. I bought the Reactor almost 4 years ago, use it all the time. It's great in a dodgy hostel or hotel 'cause it makes everything but your head bug proof. Also being in the bag is actually more reliable than any blanket/quilt etc on any bed. Once you use the liner, you'll realize that drafts you've never noticed, and still don't have actually been a problem for years. I even use it in the summer in my sleeping bag. If it's warm I'll leave the sleeping bag unzipped, even warmer– just the liner on top. These liners say 100% polyester, but they don't have that syn-stink (I checked to find the fabric and what I was pretty sure was the right material would've cost me about $45 just for the fabric. The liner cost me $55-65 (got a bit of a discount)– so no percentage sewing your own, especially if you sew like I do). The fabric, like wool, doesn't seem to pick up body odor, so they keep you fresher, and keep your sleeping bag– harder to launder than the liner–fresher. Can't say enough about them.

    Also, you know how the temperature rating of a sleeping bag never seems to actually match actual temperatures? With the Reactor liner those numbers actually mean something. I think the benefits of a liner is it's a layer, it's a pocket– no drafts. There are also some super cheap fleece liners, they're much heavier, seem pretty nice– bought one, haven't tried it yet. (The cheap ones have big square ends. If you have a mummy bag, I'd suggest sewing a big round end and trimming those corners– but not too tight. You can always sew a tighter radius and trim more later.

    A set of sleep clothes, especially socks– that's your reward at the end of the day. I've got bad circulation in my hands and feet. I noticed that if I wore two layers of smart wool socks and got my feet wet, they still got cold. It would take an hour in the sleeping bag for one foot and then the other to warm up. When I started wearing Sealskinz socks, I noticed that my feet didn't have that nice smart wool warmth– but at the end of the day, when I crawled into my sleeping bag– my feet were not numb and cold. They warmed up almost immediately. I'd recommend a cold weather multi-day. Day one smart wool, day two Sealskinz. Still love my smartwool, and a couple of layers dry will be warmer than the Sealskinz, but as soon as water is an issue I think the Sealkskinz will be better.

  22. PEE BEFORE BED. Urine can steal a lot of body heat cause your body has to keep it warm as well. The only tip I disagree with is drinking something before bed. In cold temps, I try to hydrate as much as I need for the day as early as possible and cut out liquids as long before bed so I can expel as much urine as possible before bed. I know it sucks but if you have to pee during cold nights just go and do it. You will end up being much warmer cause you don't have all the urine to warm and moving your body will increase warmth

  23. Put a kids sleep over bag inside your bag, then wrap the whole thing up in a space blanket. You will never be cold again. And our scout master use to have us eat a chocolate bar before bed.

  24. Instead of Listening to the people at REI, how about you go to your local homeless shelter and ask them? They do it everyday, day and day out.

  25. I love that REI has been making there own brand and it’s been generally lower prices than other big outdoor brands, but now it’s been getting to be the same price as all the other ones!

  26. Be careful with the hot water bottle and make sure it's tightened enough to not spill. I've burned my leg and screamed like a mofo.

  27. I dont want to act extra clever, but this clip was probably made for temperatures around -7 and within proximity of civilization. And the clip basically says: "Make sure you stay warm." Not much of a suprise….
    If you are doing pulka tours or climb high altitude mountains nothing of this applys. So for example no serious mountaineer would ever take an inflatable matrice, because in the rare case of a puncture you are dead…
    Also you need Vapourbarrierliner, pissbottles, balaclavas with adjustable nosepieces, sleeping bags, that are taped in the breathing area, woolen undies against the wetness in the VBL, triple bag systems and so on… A whole new game.

  28. Can we get some videos on tent set up? Like The REI kingdom 6 with a. MUDROOM. No videos anywhere on the mudroom

  29. In addition, put a Zippo hand warmer inside your toe box and enjoy the warm all night. Sometimes I have to place it inside a sock to keep it from getting too warm.

  30. Great…now we're going to see 'Nalgene Wookies'…stuffed critters that you put your Nalgene inside of to 'snuggle with'. And why not mention MYLAR?! If you have a bedroll / sleeping pad, and lay mylar on top of it before putting your sleeping bag down, you'll get a LOT OF ADDED WARMTH from the mylar reflectivity of heat back into the bag! I've slept at -12F on an old military rubber pad, with a therma-rest on top of it, and mylar above that…and nearly broke a sweat in a 0F bag before! Total 'sleeping system weight'? Around 10-lbs (plus 4 for the tent…not bad, for excellent comfort at -12F!)

  31. I've been wanting to try winter camping and am in N IL, still a bit hesitant. It would basically be car camping so I should just give it a go

  32. As a tip from boy scouts we get told on winter camping trips to not even use a inflatable pad, your body will use its heat to try and heat it up vs heating you up

  33. On My first camping excursion with my girlfriend we were absolutely freezing so we decided to zip our sleeping bags together and while we were sleeping we had to keep our heads in the bag because it really was cold . The problem was we were both farting like bucking horses the whole night and that bag was so so so stinky.😄😂
