Teton LEEF Lightweight Mummy Sleeping Bag Perfect for Camping, Hiking, and Backpacking; Cold Weather Option, Compression Sack Included - Moss & Sky, 0F

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.
