Big Agnes Sidewinder 20° Sleeping Bag
Description
The Big Agnes Sidewinder 20 Degree Sleeping Bag is designed for side sleepers who want natural movement and comfort without sacrificing warmth. Its ergonomic shape moves with your body throughout the night, combining the warmth of a traditional mummy bag with added space in key areas to prevent insulation compression. Insulated with 650-fill DownTek™ water-repellent down, it offers excellent warmth-to-weight performance and packability, while body-mapped FireLine™ ECO synthetic insulation reinforces high-pressure zones like the hips and feet to reduce cold spots. Additional features such as a jacket-style hood, thermally efficient footbox, and pillow pocket enhance comfort, making this 20°F-rated bag ideal for lightweight, three-season backpacking trips
