Big Agnes Women’s Sidewinder SL 20 Down Sleeping Bag

As much fun as it is to sleep on your back all night, causing you to wake up feeling stiff and sore, Big Agnes knew there had to be a better way. Enter the Women’s Sidewinder SL 20 Down Sleeping Bag. This lightweight sleeping system is specially designed to make it easy for side-sleepers to spend a night under the stars without being forced to sleep on their back by a traditional mummy sleeping bag. A centered zipper won’t get in your way as you shift from side-to-side throughout the night, and the built-in pillow barn ensures that you never leave your camp pillow far behind. Body-mapped insulation offers the warmth you expect from down, with added synthetic insulation in high-pressure areas like your hips and feet. Complete with a women’s-specific contour and extra insulation for added comfort on chilly nights, the Sidewinder is your ticket to a good night’s sleep in the backcountry.
