Big Agnes Sidewinder SL Sleeping Bag

The Sidewinder SL is specifically designed for side sleepers, with a focus on warmth, comfort, and ease of use in any position. Engineered and ergonomically contoured, this sleeping bag features body mapped insulation to optimize warmth and minimize pressure points. The technical fit and pattern of the bag allow for seamless movement from one side to the other during the night.

Constructed with features you would expect from a traditional mummy bag, the Sidewinder SL also includes down fill for lofty warmth and synthetic insulation in the hips and feet to alleviate common pressure points. The thermally efficient footbox mimics the shape of your foot while lying on your side, and the close-fitting hood keeps insulation close without sacrificing mobility. Cinch the insulated tube along the hood opening to seal out drafts and stay warm and cozy all night long.

Additional features include a unique Pillow Barn to keep your pillow in place, an anti-snag locking zipper with a draft zipper garage, and exterior loops for hanging or storing the bag. The insulation in the Sidewinder SL includes 650 fill DownTek for water-repellency and body mapped FireLine ECO Synthetic Insulation made from 100% post-consumer recycled polyester.

This versatile sleeping bag comes with a lifetime warranty and fits campers up to 6’6”. With a shoulder girth of 66”, hip girth of 59”, and footbox girth of 40”, the Sidewinder SL weighs just 2 lb. 8 oz. and packs down to 7.5 x 8 inches for easy transport and storage. Get ready for a restful night's sleep with the Sidewinder SL, the ultimate side sleeper’s dream bag.
