The Cinder is a lightweight, super-packable quilt protected by a waterproof yet breathable shell. A drawcord pulls the foot end together into a foot box for cooler nights, and three adjustable straps keep the quilt secured to your sleeping mat. Quilts are perfect for weight-conscious backpackers. The lack of a zipper and hood reduces weight and packed volume, and the broad cut provides freedom of movement. Sea to Summit quilts feature the QuiltLock system which allows quilts to connect to a Sea to Summit sleeping bag adding an extra season of warmth.

Suggested use : Travel; Car camping; Adventure racing; Cycle touring; Ultra lightweight hiking

Season Ratings : Cool Weather

The QuiltLock™ system secures your Cinder quilt to any Sea to Summit sleeping bag for another layer of insulating down that won’t slide off in the night. The premium 750+ Loft down is super warm and compressible and the ULTRA-DRY™ water-repellent treatment protects its loft from external moisture and condensation from inside the bag. The ULTRA-DRY Down™ retains over 60% more loft and absorbs 30% less moisture than untreated down and it dries 60% faster. To help combat moisture and condensation, the Cinder uses 20D Nylon waterproof/breathable NanoShell™ fabric. For backcountry enthusiasts not so enthusiastic about a restrictive sleeping bag, the adaptable Cinder quilts’ multiple configurations provide versatility for a wide range of temperatures and environments.
