The Kelty Mistral 20F Mummy Sleeping Bag is a synthetic sleeping bag for nights that drop down to 20 degrees in the backcountry. Zip up inside and catch some z's while toasty warm, without breaking the bank to get out there in the first place. The CloudLoft synthetic insulation brings the heat, while offset quilt construction and draft lock zippers prevent cold spots and drafts. Crawl into the tent, pull up the hood, and drift off to dreamland.
