Greystone 20°

Took this out on a three-day trail and the mummy shape kept me toasty when the temp dipped near freezing, yet it still packed down small enough to fit my pack without a fight. For the weight and price, it’s hard to beat for weekend trips.

The mummy cut hugs tight without feeling restrictive, and the fabric is surprisingly breathable for a 20° bag. Took it on a two-night trip and stayed warm even when the temps dipped, plus it packs down small enough that I didn't have to fight with my pack straps.

Finally, a mummy bag that doesn't feel like a straightjacket—the cut gives my shoulders room to move without creating cold pockets. I’ve used it for two weekend trips and a few nights on the couch, and the 20° rating has held up true both times.
