Celsius XL -25˚F

I’m a bigger guy and usually feel cramped in mummy bags, but this XL actually gives my shoulders and feet room to move without letting cold air in. The flannel lining feels soft against my skin, and I stayed toasty on a 20-degree night even though it’s rated much lower.

After three nights in the high Sierra at 9,000 feet, I stayed perfectly warm even when the temp dropped below freezing — the draft tube along the zipper really does its job. The extra length lets me stretch out fully, and it packs down small enough that I didn’t curse it on the hike in.

The XL width is a game changer for a side sleeper like me—no more fighting the zipper or waking up tangled. It’s warm enough for those 25-degree nights, and the extra room makes it feel like a real bed back at camp.
