FAQ

Can Treks be zipped together?

Yes - the unisex and Women's Trek can be coupled (Unisex Trek will zip to most STS Women's bags)

What does 'women's specific' mean?

Narrower shoulders, the widest point at the hips to allow a woman to assume a natural, side-sleeping position, and insulation deployed where women need most warmth.

What are the differences between the Women's Trek and Women's Ascent?

The Trek has a broader cut and is intended for travel/camping/some backpacking. The Ascent is a more technical bag for ambitious backcountry use.
