The Big Agnes Sidewinder 0 Degree Sleeping Bag is built specifically for side sleepers who need warmth and comfort during cold-weather backpacking trips. Featuring Second Generation Side Sleeper Technology, its body-mapped design moves naturally with you as you shift positions throughout the night, eliminating the restrictive feel of traditional mummy bags. Insulated with 650-fill DownTek™ water-repellent down, it delivers excellent warmth and packability, while strategically placed FireLine™ ECO synthetic insulation at the hips, knees, and shoulders enhances comfort at key pressure points.
Designed for performance in freezing conditions, the Sidewinder includes a jacket-style hood that moves with your body, a thermally efficient footbox shaped for side sleeping, and thoughtful features like a Pillow Barn sleeve and draft-blocking zipper construction. Built with durable recycled materials and rated to 0°F, this sleeping bag offers dependable warmth, mobility, and comfort for serious backcountry adventures.
