Kelty Women's Cosmic 20 Sleeping Bag: 20F Down in Deep Lake / Trellis - Size: Regular/Right Zip

What Our Gearhead(R) Experts Are Saying:"I took the Cosmic 20 on a week-long trip through the Uintas last September, and the trapezoidal baffle construction made a real difference on those sub-freezing nights near the pass.

The expanded footbox gave my feet room to breathe, which sounds like a small thing until you've spent a night in a bag that cramps them."Cold nights in the backcountry have a way of sorting out the gear that earns its spot in your pack and the gear that gets left behind.

The Kelty Cosmic 20 Sleeping Bag has been earning that spot for years, and there's a reason it remains one of our most trusted three-season companions.

From high-country campsites in late October to shoulder-season basecamp setups where temps drop fast after dark, this bag delivers the warmth you need without piling on the weight.

The Cosmic 20 is built around 550-fill down insulation with a trapezoidal baffle construction that traps heat efficiently, keeping you comfortable when the mercury slides toward the 20-degree mark.

The expanded natural-fit footbox gives your feet real room to move, a feature that makes a much bigger difference over a long trip than it sounds.

A full draft tube and collar lock in warmth at the critical points, while the dual locking zipper sliders let you vent when the night warms up.

The fully recycled shell and liner fabrics with PFAS-free DWR round out a bag that performs well and travels lighter on your conscience too.
