I’ve been using it on frosty nights in the high desert, and the fabric has that soft, brushed feel that doesn’t crinkle every time you shift. The extra room in the XL means I can roll over without fighting the zipper, and it still packs down tight enough for my pack’s side pocket.

Crawled in after a 14-mile day and the extra room meant I could actually shift positions without fighting the fabric. The mummy cut kept me warm down to freezing, and the zipper never snagged once when I was half-asleep. Solid buy for anyone tired of feeling claustrophobic in their bag.

Finally, a bag I don't have to wiggle into like a sardine—the extra roominess means I can actually turn over at night without fighting the zipper. It held up great through three chilly nights, and the insulation kept me toasty even with temps dipping near freezing. Worth every penny for a side sleep
