Reactor Fleeceweight Sleeping Bag Liner with Grid Fleece Warmth

Cold nights call for a little extra insulation, and the Reactor Fleeceweight delivers it through Thermolite® hollow-core fibers and grid fleece that trap and bounce back body heat. Expect up to 8°C|14°F of added warmth for very little weight. Stretch fleece and arm openings let you move freely, and shoulder snaps line up with Sea to Summit sleeping bags so getting in and out stays quick. HeiQ Fresh odor control helps it go longer between washes, and washing the liner instead of the bag is easier on the bag's loft. In warm weather, it works fine on its own as a light sleeping bag.
