Quilt Lock
The QuiltLock system uses the snap locks located at the shoulders and feet of Sea to Summit sleeping bags, as well as the foot box of the quilt and the quilt straps, to attach a quilt to the sleeping bag. This adds thermal performance and versatility to your sleep system: your integrated quilt now works for ultralight summer adventures and transforms your three-season bag into a four-season sleep system.
