Sidewinder 20 Long

Traditional mummy bag optimized for side sleepers. Specifically designed for the over 60% of people who sleep on their sides, the second generation of the patented Sidewinder side sleeper technology ensures warmth, comfort, and ease of use in any position you settle into. Constructed for comfort, with additional body mapped insulation to optimize warmth where you need it and provide cushioning and support at the hips and shoulders, easing pressure points and other ‘side effects’. The Sidewinder 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. Optimized profile and thermally efficient footbox is patterned to mimic body position while lying on your side.
