Big Agnes Women’s Sidewinder Camp 20 Regular

Sidewinder Camp is designed specifically for those who sleep on their sides.  With a unique fit that is plush and relaxed while keeping insulation close to the body, this cocoon style pattern creates a 360-degree wrap to give you that cozy tucked in feeling, like a hug. The Sidewinder Camp was designed as a relaxed fit for side sleepers who take camp comfort seriously. Our Women’s specific bags differ in shape and fill weight with a less drastic taper from shoulders, to hips, to feet – reducing cold spots and creating more warmth where it counts.  This bag is truly a side-sleeper’s dream!
