Side-Sleeping Backpackers
The Big Agnes Sidewinder 0 Sleeping Bag is engineered specifically for side-sleeping backpackers. Second generation side sleeper technology pairs a body-mapped mummy fit with strategically placed synthetic insulation at the hips, knees, and shoulders to relieve pressure points and keep you warm where it counts most. Down fill throughout the bag provides lofty warmth, while a close-fitting jacket-style hood keeps insulation locked in without sacrificing mobility. The Sidewinder rolls seamlessly from one adventure to the next — and from one side to the other at night.
