Sleep comes naturally with the Shut Eye, our multi-purpose, mummy-style sleeping bag that’s durable and packable for adventures that start and end at basecamp, yet cozy for a good night’s sleep so you can do it all again, day after day. From 3-season backpacking to everyday car camping, the DWR-treated polyester ripstop shell with synthetic insulation stands up to rugged campouts and iffy weather, and the inside works just as hard to keep you warm and comfortable, even if it’s wet outside. An anti-snag zipper means easy in-and-out access, and an adjustable hood cinches down to keep your head warm without restricting your breathing or favourite sleeping position.
