Experience ultimate comfort with the Big Agnes Sidewinder SL 20 Women’s Sleeping Bag, designed specifically for side sleepers. Its ergonomic design allows for seamless movement, ensuring you stay cozy and warm through every roll and turn.
Featuring 650-fill-power DownTek™ insulation, this sleeping bag offers exceptional warmth even in damp conditions, thanks to its PFC-free water-repellent finish. The body-mapped FireLine™ ECO synthetic insulation targets pressure points to keep you comfortable at the hips and feet. Made from post-consumer recycled polyester, the FireLine ECO insulation boasts a superior weight-to-warmth ratio, making it a top-rated sleeping bag for backpacking.
The Sidewinder SL 20 is equipped with a jacket-style hood that keeps insulation close without sacrificing mobility. Additionally, the stretchy mesh Pillow Barn ensures your pillow stays in place, allowing for easy adjustments from either side. The specially designed footbox mimics your foot position while lying on your side, optimizing thermal efficiency.
Crafted from ripstop nylon with a smooth polyester taffeta lining, this sleeping bag is treated with a PFC-free water-repellent finish to keep you dry. The antisnag locking zipper and draft tube work together to prevent cold air from sneaking in. Plus, exterior loops allow for easy hanging and storage when not in use.
Whether you’re planning a weekend camping trip or an extended backpacking adventure, the Big Agnes Sidewinder SL 20 is your go-to choice for a restful night outdoors. It’s compatible with most sleeping pads (not included) and comes with both a storage sack and stuff sack for easy packing.
