Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


Roomy yet super lightweight, this sleeping bag provides 3.5-season warmth without feeling restrictive. The minimalist design includes only the features you need, purpose built for ultra-light backpacking when every gram counts. Thin fabrics and highly compressible down take up next-to-no room in your backpack.

  • Vertical baffles around torso prevent cold spots
  • 1#3 YKK zipper shaves weight
