Overview
Layered microfiber PolarLite insulation mapped to the body fills the Teton bag, with extra fill in a built-out foot box and a hood that cinches around the face. A draft tube along the full length zipper blocks warm air from leaking out.
Cold weather warmth in a roomier mummy cut is why it stands out, since you can move without opening the zipper. Synthetic fill holds warmth when damp. It weighs more than ultralight down bags of similar rating.
Who it's for
Cold weather campers and new backpackers who want a warm, roomy bag with a lifetime warranty. Sleepers taller than the regular size allows should look at the longer version.
Pros and cons
- Rated for below freezing nights

- Heavy for ultralight trips
- Fits shorter sleepers only
- Packed size not listed
Performance notes
Warmth comes from layered synthetic fill placed where the body loses most heat, plus the hood and draft tube sealing gaps. Synthetic insulation stays warm when damp. The water resistant ripstop helps with tent condensation but is not a waterproof shell.
