LEEF 20˚F Mummy Sleeping Bag
Typical mummy sleeping bags are lightweight and less bulky than rectangular bags — but they’re also notorious for being too snug. That’s why we made something better. The TETON Sports LEEF Sleeping bags are nearly four inches wider and noticeably longer than standard industry sizing. Our “short” bag is roomier than the industry regular, and our “regular” is more like an industry long. And yes, our “long” is longer than any other mummy bag we’ve looked at. TETON’s LEEF bags provide superior lightweight comfort in three temperature ratings, and the pocket-friendly price will leave wiggle room in your wallet.

Honestly love my sleeping bag! I feel like a caterpillar sleeping in it haha, only downside is that the zipper broke within a week of using it and although I was able to fix the top zipper, the bottom remains broken. Other than that it has kept me snug and warm. The material is my favorite!
TETON SportsApr 27, 2023Hi Kaylee! We're so glad to hear that you love your sleeping bag, but really bummed to hear that the zipper has already broken. If you haven't already, please reach out to our customer support team by emailing info@tetonsports.com so that we can process a warranty claim for you.

It was a great bag but I was using at home in my bed. It was a bit warm. It was long enough and wide enough. I plan to use on a backpacking trip in early May on the Central coast in c\Ca and maybe in the Sierra's same time. Get back to me after Mother's Day for a better report

- JSJohn S.Verified BuyerReviewingLEEF 30˚F Mummy Sleeping BagI recommend this productRated 4 out of 5 starsMar 13, 2023Bigger than I expected.
Haven't used this yet, bought it for a 75 mi App Trail section hike I'm doing in May. But I tried it on for size, fearing it wouldn't be big enough at the shoulders. (I wear a 54L suit jacket), Surprisingly, it zipped past my shoulders, and not too snugly. It's plenty long (I'm 6'2") and appears warm enough for what I'll need. Looking forward to breaking it in, in 2 months. Only 4 stars for now, will revise based on performance in May.

It's super warm, but it won't zip up at my shoulders. A little smaller than advertised. But super warm
TETON SportsFeb 14, 2023Hi Dylan! We're glad that the bag has kept you warm thus far but hate to hear about the zipper issue around the shoulders. If you cannot zip it due to a possible manufacturing defect or problem with the bag, please reach out to our customer support team at info@tetonsports.com so that we can help solve the issue!
- JJJames J.Verified BuyerReviewingLEEF 20˚F Mummy Sleeping BagI recommend this productRated 4 out of 5 starsJan 25, 202320°? More like 40°.
Before purchasing the Teton Sports Leef 20° Munmy Sleeping bag I messaged Teton and asked if what the comfort rating on this bag was. They responded back saying that bag was comfort rated to 41°. A big jump from the advertised 20°, the bag will keep you alive at 20° but not remotely close to warm. I tested the bag out overnight in temperatures between 42-45° with only a pair of midweight thermals. I wouldn’t ever say I got “cold” but I was never warm or very comfortable. Overall the bag is still good for the price and packs down fairly small. Just know the bag is not for 20° and if you’re camping below 45° you’ll more than likely need to layer up significantly. If Teton was more transparent about their comfort ratings I would likely give this product 5 stars.
- AVArmando V.Verified BuyerReviewingLEEF 0˚F Mummy Sleeping BagI recommend this productRated 4 out of 5 starsJan 20, 2023Zipper issues
Although comfortable and warm, it’s very slick and I slide on slopes, but my main concern is the zipper, I had a 4 day camping trip, on the very last night my zipper jammed, it could be just a little tougher thanks
TETON SportsJan 24, 2023Hi Armando! Thank you for your review and feedback about the LEEF sleeping bag. If the zipper continues to jam, please refer to the video below to fix the jammed zipper. We've also heard that lubricants such as Vaseline, candle wax, or bar soap will help the zipper to glide easier and prevent the zipper from jamming. If there seems to be any defect in the workmanship of the zipper or bag, please reach out to our customer support team at info@tetonsports.com!
