OUR CLASSIC BEST-SELLER - THE PERFECT BALANCE OF LIGHTWEIGHT WARMTH Remember the trapezoid from high school geometry? Turns out, this funky ol' shape is ideal for helping sleeping bags retain heat. Our trapezoidal baffle construction is just one of the reasons the Cosmic Down is still our favorite three-season superstar. We also love the expanded natural-fit footbox for happier feet, zippered stash pocket and fully recycled fabrics and PFAS-free DWR treatment. The Cosmic Down is the total package.

Customer Reviews (4.8 / 5 · 5 reviews)

Ryan ★★★★★

The trapezoid shape sounded gimmicky until I crawled in on a 20-degree night and stayed toasty till sunrise. Bag’s still impressively light for how much insulation it packs, and the zipper never snagged once.

Claire E. ★★★★★

Woke up at 5 a.m. on a frosty trail and my toes were still warm — the trapezoid cut really does lock in heat better than any mummy bag I've used. Feels like it packs down smaller than the spec sheet suggests, too.

Sophia ★★★★★

The trapezoid shape actually works — I stayed warm all night at 28°F without waking up cold once. It packs down smaller than my old mummy bag and the draft collar seals in heat way better than I expected.
