Specifically designed for those who sleep on their sides, the patent-pending Sidewinder Series was engineered to ensure warmth, comfort, and ease of use no matter which side you’re on.

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.
