Big Agnes Women's Sidewinder Camp 20°

The Big Agnes Women's Sidewinder Camp 20° is built around Big Agnes' Sidewinder cut, a cocoon-style pattern designed to rotate with the sleeper rather than lock them into a fixed mummy shape — a genuine advantage for side sleepers who shift position through the night. FireLine ECO recycled synthetic insulation (1092 g fill) brings total weight to 1328 g and a manufacturer-rated comfort temperature of -7°C (20°F). At that weight, the Camp designation is accurate: this is a bag built for car camping and established backpacking base camps rather than long trail miles, where the Sidewinder SL versions in the same family are considerably lighter. A dual-side, full-length zipper and draft collar and tube seal the fitted, contoured hood area, and the nylon ripstop shell with polyester taffeta liner takes on the rougher handling of camp use better than delicate ultralight fabrics. Sized for users up to 165 cm, with stuff and storage sacks included, this is a straightforward, PFC-free option for anyone who prioritizes side-sleeping comfort over pack weight.
