Style & Size:


Think of it as your bed sheet.

Cozy into Western Mountaineering's Sonora Sleeping Bag Liner at night, and you might think you're waking up in your bed even though you're camping. This liner's polyester construction feels as soft as your bed sheet back home, and it adds warmth if you're too cold and moisture management if you're too warm. This liner is machine washable so it doesn't smell like last trip's campfire, and Western Mountaineering included a stuff sack so you can take it backpacking.

Great pad cover for quilt backpacking

I've put it through the wringer

I've been using this for a few years mostly slipped and cinched over my tapered thermarest 20" sleeping pad. I tested it on a 25" pad and it fits on that size also. This gives me a nice sheet feel to my pad since I use a quilt. It has held up great and still looks new. I machine wash and dry on low it occasionally.
