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.

An Ember quilt can be an ideal light and packable option for bikepackers, ultralight hikers and travelers. Constructed using high quality 850+ loft Ultra-Dry Down and featherweight fabrics, this well-constructed quilt offers freedom from the weight of a sleeping bag zipper and the freedom from the constrictive shape that comes with some sleeping bags. The Ember Series takes the simplicity of the quilt concept a step further - snap-on attachment straps keep your quilt located on your sleeping mat, while the drawcord base of the 50°F and 35°F give the Ember a shape-shifter' function: wider at the base for more freedom of movement when it's warm, snugged down when it's cooler. Embers also add multi-season functionality: the QuiltLock system allows an Ember to be attached to any hooded Sea to Summit sleeping bag to boost thermal performance in colder weather.
