Teton LEEF Lightweight Mummy Sleeping Bag for Camping, Hiking, Backpacking; Cold Weather Option, Compression Sack Included

I got home yesterday from what was supposed to be a 2 day solo trip up to the Boundary Waters area in Northern Minnesota. Going up there I knew this trip was going to be cold - Initial Impressions on first arrival of this bag. Fluffy, this bag has tons of loft for a synthetic. It is nice and fluffy. I laid it out, crawled in and within in about a minute started to sweat. It was 70 degrees in my house. The zipper on this thing is tricky. It says it is a no snag but I was having it get caught on the fabric about every 12-14 inches. Comes with a compression sack which is great at this price point. However, it does not compress down very much. Totally fine with this for the price point. I pulk a sled when I winter camp so space is not a huge deal. If you are backpacking, this took up 3/4 of my 60L pack. It will not leave much room for other stuff. - Using this bag in the field. The first night I got up it was supposed to be -26f out for a low. To think this bag by itself would keep me alive would be stupid. For the inside of this bag I put a 40f degree down top quilt from massdrop. Personally I would rate it at 30f but whatever. Underneath me I had a thermarest z lite on the ground. I think that has an R value of 1 point something.. On top of that I had the Lightspeed Outdoors self inflating sleeping pad which has an R value of 8.7. Know that in cold weather none of your self inflating stuff will inflate. You must blow it up. Also, if you plan to winter camp you will NEED 2 sleep pads to insulate you from the ground. When I went to bed at 10pm it was -32.4f outside and my tent stove kept the inside a balmy 16.7f. At 5:30 when I woke up it was -36.4 outside and my stove had long burned out and it was -30.4 in my tent. I was totally warm and not uncomfortable in the least. I would have taken a picture but there was no way I was opening up my bag to stick my arm out and let cold air in. That night while crawling into the bag and zipping up, I again had some issues with the zipper. It kept getting caught in the material. You really need to go slow and use your other hand to make sure things are not snagging. Not always easy to do while in a sleeping bag. The fit of the bag is great. I have broad shoulders, am 6'2" and 190lbs. I did side sleep part of the night and still kept warm. Even with its short comings of tricky zipper and not compressing down much. You will not find a better deal on a 0 degree bag for under $100 bucks. Btw, I only ended up doing 1 night. The next day, the Park Ranger came by and said it was going to be 40+ below the next night so I opted to play it safe and leave. The temp there actually got down to -49f so I'm glad that I left. HIGHLY RECOMMEND!!!

To get to the point, I debuted this bag on a camping trip in early December 2022 in the NC Appalachians near Banner Elk in rainy conditions and one of the nights it got down to 33 degrees... I wore literally nothing in the bag the first night just to test its conditions and it really did keep me warm! An issue is that air comes in through the facial hole in the mummy bags so you'll want to find a way to block that without suffocating, but it's better than the alternative. Teton Sports is a great company that, as you can see, is actually active on this page answering questions, I'd definitely listen to them that 0 F degrees actually means you will be kept ALIVE in the bag down to this temperature, but it will begin to be an uncomfortable night at 20 F degrees instead, so read '0' more as '20'. If you don't live in some extreme environment, this is a great bag. Anyone in the southeastern US should be just fine with it. If you bundle up inside it, you're even better off. I also want to say that this thing is more comfortable than my bed. When I entered it the first time, it was like entering some kind of advanced spa. I felt more relaxed than I had ever before, but you're going to get really hot in there if you aren't in the cold! If you get cold easily, perfect. If you stay warm, you'll probably think its even more comfortable in winter weather, which it really can hold up to. My tent got water inside it somehow during those nights last month (it's not supposed to) and you couldn't help but have the bag touch the water... unless you're really tall (like, REALLY tall), you aren't going to take up this whole bag, especially when curled up in the winter weather, so it wasn't an issue. The water didn't soak the whole bag or spread in it, but then again it was so cold maybe I couldn't tell. The only con I would say is that this kind of polyester gets cold very easily, so entering this bag in under 40 degree temperatures is going to feel horrible for about a minute but it warms up extremely fast. I was amazed, inside the bag, reaching out to touch the outside where the bag's surface felt so cold but inside it it was very warm; this thing retains heat very well. I wish they'd make a version of this bag in some kind of hybrid cotton and in warmer colors, you feel like you're entering an alien pod in these colors, but they are really cool to look at and the green exposes any stains or debris in the bag while the external black makes it harder to find stains or issues. The dirt from the wet parts of the tent dried to the bag and wiped off easily, also a nice feature, the bag 'wicks' debris off its smooth surface quite easily. The manufacturer and label claims you can't wash the bag and it voids warranty if you do... that last part might be a problem, but you can absolutely wash the bag. I wouldn't do so OFTEN, considering I did with my Teton Sports camp pillow and it made a hole in the pillow, but you can do it... the idea that you just let your bag air out/stay dirty or wash it by hand is pretty absorbs, no one wants to be doing that. On the road trip, I opened the bag and let it air out and it didn't really smell anymore, though the smoke scent is pretty inescapable even after washing it.

TLDR; internal fabric was uncomfortable for me, and the short size was much smaller than anticipated (I'm 5'3, it's rated for folks under 5'7 and I barely fit in it). Despite using it incorrectly (as a sleeping quilt) because it was too small, it prevented me from getting cold in a 35° alpine storm. Would recommend, just make sure to get the sizing right and be prepared for a cotton interior. I want to start by saying I really wanted to like this bag. I was so excited to get it, it was my first nice backpacking bag and I knew it was going to be pretty chilly on our upcoming trip so I wanted to get a proper bag. I read so many reviews raving about it, and I was so stoked to give try it out. I ordered the short size because I'm 5'3 and they say the bag is 6'3 and for people under 5'7, so I thought it'd be a good fit. I was wrong 😞 I tried the bag out when it came and it just barely fit me from foot to head. Once in it, I couldn't move at all. Again, I was so excited by the bag that I thought I'd be able to make it work, so I decided to bring it on the trip. Our first night out, we were camping in a cloud so it was chilllllyy. I got in the bag and it was toasty, but the cotton fabric on the inside gripped my fleece leggings and sweater so I really couldn't move. I ended up getting claustrophobic, completely unzipped the bag and used it like a sleeping quilt instead. The second night out, we were camping at 5000 ft and a storm rolled through in the night. The temp dipped to 35°, with incredible winds and rain beating on the tent. The reason I say this is despite me not using the bag correctly, I didn't get chilled. Sure, there were points where I was absolutely not warm, but I wasn't shivering and I was able to get comfortable enough to sleep upon repositioning. The issues I had with the bag are like 75% on me for not doing better research or getting the bag earlier on for a car camping trip that I could have had a backup on in case I didn't like it. The fabric on the inside is incredibly warm and truly is just a preference thing for me! As for the sizing, I should have looked more in depth into the specs, and I recommend folks do it as well. The short size is probably better suited for kids than adults. Despite my issues with the bag that's causing me to return it, I still recommend it! It is a reasonable weight for backpacking, compacts and rolls super well (it fit in my 45L bag), and is super warm.

This bag is a life saver if you let it. Its super roomy I’m 5’8 and 155. I’ve bought both the regular and long, I recommend both as they are no different just the amount of room and from a weight stand point you won’t no the difference. I put this thing through the whirl wind. Literally. It holds up on the most extreme weather without a tent! 0 degrees is a check and comfort is without a doubt. You still may want to purchase a pad for extra comfort no reflection on the comfort and pillow like environment of the Teton bag. As far as extreme cold it will hold up in extreme 0 degree temps. Literally no need to worry and your not going to be cold. It’s actually baffling as to how it is you end up not only warm in the teens but actually feel refreshed in the morning fear not the cold with this bag. In the extreme wet and rain storms you have nothing to fear as well. You can actually use it for cover and extremely rainy conditions. This bag will save your life if needed. It has the capabilities. It is no joke. Its great as a blanket and super cozy and comfortable. As far as backpacking it will fit perfectly in a 75 liter zipper pouxh (see backpacks I recommend either Teton or Amazon’s basics obviously it fits fluidly and is light as a feather for all day hiking) Its like air, and super compressible. as far as comfort it’s nicer than my bed. It feels like a cloud to lay in. They are a fantastic company and excellent in customer service and are there for you and the products have a Guarantee that the company stand behind. They have a very bright future. All and all super easy and light to carry and it matches both the description exceeds your expectations. You will love this sleeping bag and nothing to worry about in any condition. It’s like a heated bed and blanket that holds ups to 0 degrees and extreme tempayure at a whopping three pounds and is lighter than air as you lay on a cloud. Go with the longer version for extra comfort and some addition space 😉

I bought my LEEF sleeping bag a little over two years ago before a three week road trip to Alaska, and since then have probably spent 60 to 70 nights sleeping in it between various roadtrips and overnights stops at friends’ houses. I really like that the bag keeps me warm regardless of temperature - the only time I’ve ever felt cold was during brutal winds at 11,000 feet up the side of a mountain in Colorado, and without windchill temperatures were around 10 degrees F. Due to poor setup of our tent, wind was able to go underneath our rainfly and blow directly onto me, so I blame user error for that one, not the bag. After extensive use, the LEEF bag has held up very well. Before I pack it up after a trip I am always sure to clean it and let it air out for a few hours, but other than that I haven’t felt a need to be terribly delicate with it. From the mountains of Alaska to the beaches of Mississippi and Louisiana, this bag has served me well and it no worse for the wear as a result. I’m also very impressed that despite spending 75% of the year compressed into a storage bag, the sleeping bag itself hasn’t deformed and become lumpy, as so many other bags I’ve had do. I only have two minor complaints about the bag. The first is that it takes some practice to be able to roll it up and fit it into the carrying case - I’d suggest doing this a few times at home before attempting it on the trail. The second is that despite me being a relatively small person (5’6”, 135 pounds), I do feel a little cramped when I zip the bag all the way up. This is, of course, the nature of a mummy bag, but I feel it is worth forewarning that if you are the type of person who rolls around a lot in your sleep, you may want to try out a friend’s mummy bag before buying one yourself. I’ve never found myself unable to sleep on account of the bag being too small, but sometime it does take a little more adjusting to get comfortable than it would take me in a traditional sleeping bag. If a larger concern is space conservation in your bag rather than extra wiggle room while sleeping, then this bag is perfect. I’ve fit it into my hiking backpack with zero issues, and appreciate that the carrying sack has straps on it that can ratchet down and compress the bag even more to fit into smaller spaces. Overall, this sleeping bag has served me well for several years and I hope to keep using it for years to come. At only around $70, this is a very good investment and I have been very happy with quality, comfort, and size. I couldn’t recommend strongly enough!

I love this sleeping bag. If i were to have one sleeping bag for the apocalypse, it would be my 0degree leef. Why? It's not just a value for the money, though obviously, this is the best value-for-money sleeping bag on the market. It's because it is general purpose and durable. Is it really a 0 degree bag? I don't know. When its in the mid-30s I wear long underwear and sleep curled up, and then am completely fine (for reference, I am a cold sleeper. No bag is ever warm enough once it approaches freezing). If it's colder than that, I'd wear more clothes. I don't think it's really a 0 degree bag, maybe a 15-20 degree bag. But: it's durable and synthetic. Synthetic bags are cheaper, slightly heavier, and don't pack down as well. But when they rip, you can just keep using them, or patch them up. When they get wet, they still keep you warm. If you cowboy camp, a synthetic bag is better. If you're not expecting to just be able to buy a new sleeping bag, a synthetic bag is better. This bag is light enough that if you need you can bring it backpacking. I might not suggest it for a thru-hike. i lived out of a backpack and cowboy camped most nights for ten years, and a big ole synthetic sleeping bag is about the best thing in the world. When it was too hot, I just unzipped it. When it was too cold, I just wore more clothes. Now, it's NOT the apocalypse. It might be nicer to have a down sleeping bag for backpacking, or one that is rated for warmer than 0 degrees for most seasons. This isn't the best sleeping bag for most situations. It's just the one that CAN work for all of them. If i were to own one sleeping bag, it's this one.

So my last budget sleeping bag purchase didn't perform to standards at all, so despite researching many bags before settling on this one, I was nervous. I bought the 0f bag figuring it can cover what my old bag wouldn't. My old bag was a 20f, but it was incapable of keeping me warm at 40f, I had to use a fleece liner and down blanket to keep warm. So first of all, incase you are unfamiliar, sleeping bags in this price range are not rated for comfort temperature, they are rated for survival temperature. You should expect to be comfortable at about 20f above the rating if you dress in cold weather sleeping attire and insulate yourself from the ground. So for reference, I am 6'2" 220lb and wear large shirts and pants, size 13 feet. I found the dimensions of the bag to be perfect for me. It is 2" larger in every dimension from my old bag, and the footbox is adequate. For my test, I slept out in a lean-to tarp shelter with an overnight low of 22f. I laid out a space blanket and a 4.4R inflatable pad for ground insulation. I'm not really a back sleeper, so I had some concerns about the "body mapping" insulation not being there on the bottom. My concerns were alleviated, I turned half the night like a convenience store hotdog like I usually do, and found no cold spots. Getting back in after a late night pee is always chilly, but lift the insulation and blow down to your feet a few times, your hot breath warms the bag back up in seconds. The zipper is about on par with everything else I have. It's strong and not prone to getting off track, but has a tendency to snag when zipping up from the inside. I have yet to see a bag that doesn't... The Velcro flap at the top stops it from coming open under tension, but I found I liked having the top few inches of zipper undone so I could move my arms. Lastly, the materials. The outer shell does a good job of blocking wind and moisture, and seems pretty durable compared to other bags I've had. The inner fabric is soft, but doesn't snag like flannel. It feels like microfiber bedsheets, which I use at home. And the insulation, the loft is impressive. For the first time, I was actually amazed I got a bag back into it's stuff sack. I put the footbox in the sack, and it's full... Yet, you can actually keep stuffing and get the whole thing in there. Now a note on the sack, I'd give it 3 stars if I could rate it separately. It does it's job fine so far, but for some reason they felt compelled to sew a band around the lower part of the sack about 3" above the bottom seam. This is the point the compression straps are sewn to, rather than looping under the bottom. This concerns me that it may burst that seam over time. It doesn't even look like they saved any material in the process, it's just plain stupid. Overall, extremely pleased with my purchase.

The bag itself is well made. I got the zero degree version and I have no doubt this would keep me warm most nights unless the temperature got below like 15 degrees Fahrenheit. I'm giving it three stars because even though they give you the specifications and they're very good about it prior to ordering. The problem is you don't process it cuz you're used to bags made for normal size people and this one definitely runs a little small. the shoulder width is rather narrow and constricting. I'm a normal size adult to Unfortunately the only other option is the large I wish they would just spend a little more money by more material and make the bag a normal size for a normal adult.
