New – Sea to Summit Glow GWL 50F Synthetic Integrated Quilt Sleeping Bag. The Glow quilt is a really lightweight summer quilt insulated with continuous-filament synthetic insulation ideal for conditions where you might encounter moisture. 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 not for everyone, but many weight-conscious backpackers choose a quilt over a sleeping bag for warmer-weather use. The lack of a zipper and hood reduces weight and packed volume, and the broad cut provides real freedom of movement. Sea to Summit quilts have an additional advantage: the QuiltLock system means that the Glow can be connected to a Sea to Summit sleeping bag adding a whole extra seasons warmth to your sleep system.
