The Drifter series sleeping bags are constructed of a durable, polyester ripstop shell, lined with a soft, smooth brushed polyester and filled with synthetic TechLoft Silver insulation. TechLoft Silver insulation consists of multiple denier staple-length fibers that have a siliconized finish for maximum insulation, loft, and compactness. The bags feature two-layer offset construction with an insulated chest and zipper baffle to lock heat in. The Drifter offers a unique, tapered-rectangle design which allows for more wiggle room than a mummy bag, and more heat retention than a traditional rectangle bag — providing you the best of both worlds. If you are camping as a couple and want to snuggle up close, the Drifter bag design allows two bags to zip together creating a double bag. Even better yet, the two bags can be the same or different temperature ratings to maximize comfort for each person. The design also features a second side zipper allowing you to fold back the top for home-like comfort or allowing multiple venting options when two bags are zippered together. A standard stuff sack is included for easy transport and storage. The versatility — not to mention to eye-catching colors — make the Drifter a must-have for your next camping trip. SKU: 4500402
