Whether you're road tripping or backpacking, there's never a reason to sacrifice quality sleep over dependable camping gear. Transform your setup with the Synthesis 35, our do-it-all sleeping bag that combines our SierraLoft™ synthetic insulation with lightweight, durable materials that are typically reserved for more premium sleeping bags. Its dual, anti-snag zipper system makes sleepy midnight adjustments easy, and a draft collar along the zipper prevents uncomfortable cold spots from touching your skin. To help you fine-tune your temperature, our patented self-sealing foot vent adds instant ventilation at the toe, while the cinching hood locks in heat at the head (and doubles as a barrier when your pillow likes to run away). Plus, with a durable water repellent (DWR) treatment, a little rain will never ruin your peaceful night.
