Women's Greystone 20°

Took this on a three-day backpacking trip and slept warm even when the temps dipped to around freezing. The mummy cut hugs tight without feeling restrictive, and the 20° rating actually held up through the night.

Used it for a chilly couch-surfing night and the mummy fit kept me toasty without feeling constricted. The 20° rating held up better than I expected, and it packs down small enough that I didn't need to rearrange my whole car.

Took this out for a three-night trip and the mummy cut kept me warm down to the low 20s, no cold spots even when I rolled around. Weighs next to nothing in my pack, and the zipper never snagged once, which is rare for me.
