Side sleepers, rejoice! The Big Agnes® Sidewinder Camp 20° Mummy Sleeping Bag features a unique design that side-sleeping adventurers will appreciate. Featuring an ergonomic design that's contoured to keep the body-mapped insulation next to your body without cold pockets when sleeping on your side, this Big Agnes mummy bag provides ample warmth while minimizing pressure points. The long, ambidextrous zipper with an anti-snag performance and draft-free garage stays out of your way while on your side, and the cocoon-style hood traps extra warmth. Filled with FireLine™ ECO Insulation that's made from 100% post-consumer recycled polyester, this sleeping bag maintains high loft and weight-to-warmth ratio, while also being easily compressible and exceptional durable. The nylon ripstop shell and polyester taffeta lining both boast a PFC-free durable water-repellent (DWR) finish. An internal cord lock lets you adjust the hood without unzipping, while at the other end a thermally efficient footbox mimics the shape of your feet when lying on your side. Includes a draft collar and hand pouches. Exterior loops let you easily hang for drying or storage. Comes with a storage sack and a stuff sack.
