Women's Sidewinder SL 20°

The side-entry zipper makes a huge difference when I'm half-asleep and need to roll over without fighting the bag. I'm a restless sleeper and the extra room in the shoulder area lets me stay on my side all night without that pinched feeling.

I wake up with less shoulder pain than I do in my own bed, which I never expected from a mummy bag. The hollow on the side for my arm makes it so easy to shift positions without fighting the zipper or losing the draft collar.

Tossed and turned my way through countless bags before this one—the patented side-sleeper cut actually lets me bend my knees without the insulation compressing under me, and the footbox has room to spare. Woke up without the usual cold draft along my hip, which never happened with my old mummy bag.
