Designed to sleep warmer, pack lighter, and move with you, the Kelty Women’s Cosmic Ultra 20 is a three-season sleeping bag built around how women actually sleep outdoors.
This lightweight mummy bag takes Kelty’s proven Cosmic design and refines it with women-specific geometry and premium materials. Narrower shoulders, wider hips, and a shorter torso create a better seal, while extra insulation in the upper body and footbox helps counter the fact that women tend to sleep colder. The result is more efficient warmth without unnecessary bulk.
At the core is 800-fill DriDown insulation, delivering excellent warmth-to-weight performance with added moisture resistance. Trapezoidal baffle construction improves heat retention by keeping insulation evenly distributed, while the buttery-soft 20D nylon shell and liner feel comfortable against skin. A natural-fit footbox gives your feet room to relax, and thoughtful details like an internal stash pocket and anti-snag zipper make camp life easier.
Built for backpacking, shoulder seasons, and anyone who prioritizes comfort without carrying extra weight, the Women’s Cosmic Ultra 20 balances performance, packability, and smart design.
