This is a review of the Teton Sports LEEF sleeping bag.


The TETON Sports LEEF -18°C/0ºF Ultralight Sleeping Bag uses innovative PolarLite micro fiber insulation which helps cut weight without sacrificing comfort and warmth. The 3-piece no gap hood adjusts around your face to keep the heat in and cold out. Taped, anti-snag zippers with a full-length zipper draft to eliminate any cold spots. 87 inches x 34 inches (at widest point) provides more shoulder and leg room than most mummy bags, yet it can be compressed down to maintain pack space. Weighs 4.2 pounds.

The Teton Sports LEEF is the third Teton Sports sleeping bag we’ve reviewed, and it honestly seems to be the best quality of the bunch so far.

For a 0 degree Fahrenheit bag, this is pretty warm and comfortable and has very solid construction. At use around 10-20 degrees, you’ll still feel warm. Usually with the zero degree bags, they end up feeling kind of cheap and maybe aren’t as warm as you’d like as they are designed to also be lightweight. Teton Sports has forgone some of the lighter materials to make the bag better quality and warmer.

At 4.2 pounds, this really isn’t that heavy. However, you can get backpacking bags that are as little as 2 pounds. As a backpacker, you will need to decide whether you want to carry the extra pound of weight while also having a super comfortable bag that is high quality, or if you want to spend more to get something lighter which might not be as comfortable.

This bag packs up to be 15 by 9 inches in a stuff sack. That makes it possible to use for backpacking as it will fit in a sleeping bag compartment or in your backpack. Some people have complained that the sack is tight, but it really is supposed to be so that this takes up as little space as possible. It does fit in the sack.

The construction and materials feel high quality and the bag looks like it will last for a long time. Honestly, I think this is  a pretty high quality bag, especially given the price. You just have to decide if you can live with a 4.2 pound bag.

I would high recommend the Teton Sports LEEF 0° sleeping bag.
