Big Agnes Sidewinder SL Lightweight Sleeping Bag

Feature Highlights

For Side Sleepers

Technical Fit for Optimal Comfort Our nylon sleeping bag is specifically designed for side sleepers, providing a technical fit that moves with you as you roll from side to side. Body-mapped insulation optimizes warmth and minimizes pressure points, ensuring a more restful night’s sleep.

Down and Synthetic Insulation Combination Featuring down fill throughout the bag for lofty warmth and synthetic insulation in the hips and feet, this sleeping bag alleviates common pressure points. The combination ensures supreme comfort and minimal disturbance during the night.

Warm and Cozy

Optimized Fit and Warmth Our sleeping bag is optimized to fit your body while lying on your side, mimicking the shape of your foot position. The thermally efficient footbox and close-fitting, jacket-style hood keep insulation close to your body without reducing mobility. Secure yourself against drafts by cinching the insulated tube along the upper hood opening, ensuring warmth and snugness all night.

Additional Features

Pillow Storage and Easy Adjustment The unique Pillow Barn, made of stretch mesh material, allows for easy adjustment and secure storage of your pillow. The smooth, quick zip with an anti-snag locking zipper and no draft zipper garage ensures easy access and prevents discomfort during the night.

Durable and Easy to Store Designed for ease of use, the long, ambidextrous zipper stays out of your way when sleeping on your side. Hang dry or store your bag using the exterior loops. Included are a storage sack and stuff sack for convenient packaging.
