      Great bag

      This is my 7th purchase of Teton Outdoor equipment and they never disappoint. This is a warm and roomy sleeping bag. Lots of comfort for a mummy style bag. Not at all claustrophobic. Will really come in handy on my hiking trip in the Sangre de Cristo mountains. Along with my Explorer 85, sports vista tent, and this bag, I am set up for comfort.

      Great

      Soft and comfy. Definitely warm. Doesn't compress down to small but it's doable.

      Very warm, very narrow

      My wife liked how warm the sleeping bag was in cold temperatures, but she didnt have any space to move around and could barely fit in the bag. Also, the sack that holds the bag falls apart pretty easily.

      Hi Roger!

      Thanks so much for sharing your review and for choosing TETON products. I am wondering if your wife is possibly using the short version of the LEEF '21? Our regular size in this mummy bag is generally considered above industry standards in terms of sizing with the following measurements 87" x 34" (at the shoulders) x 22" (at the foot). If you'd like to talk to our customer experience team to see if possibly she needs a different size or if there are other options in a mummy bag that might be a better fit for her, please send us an email: info@tetonsports.com. Happy camping!

      It fits!!

      I haven’t tested the temp rating yet but I can say that this is the first mummy bag that has me! I am 6’1 / 250 with a 50 inch chest and I have only ever been able to use a mummy bag like a quilt. It’s big, warm, and compresses down to fit in my Explorer 4000 sleeping bag compartment. Big fan of you guys! Thank you!

      Excellent sleeping bag at a great price! Tested this bag out last night and it exceeded my expectations. The temperature dropped to -10F and I stayed very warm. Also used a sea to summit reactor liner, kokatat fleece onesie, and two sleeping pads. With more layers I feel I could push this to far colder temps. Despite the outside of the bag being iced up with condensation I stayed very warm and dry. I am a warm sleeper, but I would expect most to be comfortable down to 0-10 degrees with a few layers.

      Very comfortable bag. It compresses very well for a synthetic sleeping bag and is relatively lightweight. Had it for over a year now and it has not disappointed. In a damp climate it does extremely well until -15c (with a good pad). -18c is not uncomfortable.

      Recently had a small issue with my Teton leef sleeping bag, but after contacting Teton their amazing customer service team immediately got back to me and resolved the situation! Definitely one of the best experiences I've ever had with customer service. Thank you!

      We used the Leaf 20 bags on a recent 3 day hike in trip to the Manistee River Valley (Michigan). These bags are relatively light, pack down well, and fit easily into the bottom compartment of our packs. Forecast lows of 50 F, but we could see our breath early morning while set up next to the river - we all stayed warm and slept well. Something we discovered while using these is that if you feel 'closed in' you can unzip the bag, turn it over, keep your feet in the footbox and use the rest of the bag as a blanket. This worked really well. The bags are designed larger than the mummy bags I have used before, and allowed for a fair amount of movement. Fabric is comfortable, insulation is warm, quality is typical Teton. Can't beat the price either. We use these in place of our Celsius bags due to their pack down size and weight - will keep the Celsius for car camping... Highly recommend these bags for their value!

      After many hours/days of research and countless hours of looking up reviews I decided to buy the Teton Leef 0. I found out about Teton when I was looking at buying a travel pillow and bought their Teton Comfortlite self-inflating pillow, which I absolutely love!

      I can't believe how well made this bag is and the comfort is outstanding. All of the reviews out there speak about the plush and soft interior lining and they are not wrong...it's that nice. I wanted a bag that was as lightweight as possible without sacrificing warmth and there doesn't seem to be any bag at this price point that comes close. I am 6'2', big and really like to move around and thought a mummy style bag would be restricting but the generous dimensions of this bag gives me ample room to move and shift. The zipper is butter-smooth and the weight at 4.2lbs is certainly manageable for a bag that is a 0 degree rating. Fits back into the stuff sack easily and the straps on it allows it to be compressed to a size of a basketball.

      When I spend this amount of time researching products it is rewarding when the gear lives up to the high standards I set in my mind. Teton matches this...so I also bought the Mountain Ultra 4 which I'm excited to have arrive next week.

      Special shout out to the customer service team at Teton as I had questions on some of their gear and they were the best I've dealt with.

      Such a great company. Congrats.

      I have owned this bag for a few years now. Having slept in it under some fairly extreme conditions, including a 10 degree bivouac above tree line and just above 0 in a tent, I have stayed warm in this bag and I'm a cold sleeper. It's a bit heavy but for the price it's hard to beat.
