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.

  • The LEEF comes in short, regular, and long, so you can rest in comfort.
  • Choose from three temperature ratings: 0 degrees, 20 degrees, or 30 degrees.
  • Four inches wider and noticeably longer than standard industry sizing
  • Superior lightweight comfort
  • Lifetime Warranty

      Seems a tad shorter than advertised dimensions state

      Seems a tad shorter than advertised dimensions state

      I am 5'11" and honestly I am not sure I am goign to be able to fit into this

      I might have to return it for the long version

      I went with the regular length so it would fit in the not so true to size 85L explorer I setup just for hammock camping

      Thank you for reaching out with your concerns about the sleeping bag dimensions. Our measurements are taken at the factory before the fill is added and when the material is fully stretched, to ensure the most accurate dimensions possible. It’s important to understand that once the fill is added, the loft of the fill can cause the sleeping bag to appear a few inches smaller due to the natural compression of the material.

      Additionally, slight variations between production batches are normal and can occur due to the intricacies of the manufacturing process. These variations are typically within a few inches and are considered standard in the industry.

      If you find that the regular length does not comfortably accommodate your height, the Long version might be a better fit for your needs. Please don’t hesitate to contact us for assistance with an exchange to ensure you have the right gear for your hammock camping. We're here to help!

      My cocoon🐛

      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!

      Hi 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.

      Second part opinion

      Seams to be of good quality and my son is happy with it. It fits in the bottom compartment of a backpack from same manufacturer.

      Great sleeping bag

      This is a great sleeping bag keeps you warm all the time plus it’s a lot better than the stuff they give us and it’s lightweight and compacts much smaller as well
