Sidewinder SL 20°
Description
Specifically designed for those who sleep on their sides, the patented Sidewinder Series was engineered to ensure warmth, comfort, and ease of use no matter which side you're on. 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 and other 'side effects'. The Sidewinder SL is a side sleeper's dream bag with technical features that roll seamlessly from one adventure to the next, and from one side to the other at night. U.S. Patent 11957260 B2
