Relax and Sidewind

After a long day on the trail, sometimes you just need to relax and unwind. But that can be hard when you're forced into a rigid sleeping position on your back. Don't worry, Big Agnes has you covered with the Sidewinder SL 35 Down Sleeping Bag. Designed for campers who sleep on their sides, this lightweight sleeping bag is specially constructed to move with you throughout the night from one side to another. Packed with lightweight, water-resistant warmth in the form of 650-fill Downtek, the Sidewinder is also equipped with body-mapped synthetic insulation at your feet and by your hips to keep pressure points to a minimum. And since it's a Big Agnes sleeping bag, it comes with everything you know and love, like an integrated Pillow Barn, insulated draft tube, and a tough shell fabric to ensure that this bag will be in your arsenal for years to come.
