Big Agnes Sidewinder SL 20

The Big Agnes Sidewinder SL is a light synthetic filled sleeping bag designed specifically for those who sleep on their sides. Constructed with features you expect from a traditional mummy bag with additional body mapped insulation to optimize warmth where you need it and minimize pressure points. The Sidewinder SL is a side sleeper's dream bag with technical features.

The Sidewinder SL has a lightweight nylon ripstop outer and comfortable polyester taffeta lining, both with PFC-free water repellent finish. For insulation the Sidewinder SL uses a body mapped combination of 650 fill power DownTek down with a PFC-free water repellent treatment, with FireLine ECO Synthetic Insulation at the hips and feet, as these areas are pressure points for side sleepers. The FireLine ECO synthetic insulation is made from 100% post-consumer recycled polyester.

The Sidewinder SL features a Smooth, quick zip with anti-snag locking zipper with no-draft zipper garage, and long, ambidextrous zipper. The Hood is easy to adjust from inside the bag using internal cordlock access.
