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.

Penelope R. ★★★★★

Took this out on a frosty weekend and stayed toasty all night—the trapezoid cut really does lock in warmth better than my old rectangular bag. It packs down small enough that I barely noticed it in my pack, which is exactly what I wanted for backcountry trips.

Ellie ★★★★★

The trapezoid shape sounded gimmicky until I actually slept in it—I stayed warm all night without that suffocating bulk. Packs down small enough that I barely noticed it in my backpack.

Owen I. ★★★★★

Weighed it on my kitchen scale before a weekend trip and it came in even lighter than the specs promised, which is huge for my pack. The trapezoid cut actually keeps the warmth locked in better than my old mummy bag, and I stayed toasty through a 38-degree night without overheating.
