Key features of the Sea To Summit Reactor Fleeceweight sleeping bag liner
Thermolite is a hollow fiber that allows air to be trapped inside, as well as in the knit of the fabric, providing more warmth for its weight than any other lining fabric we use. Excellent breathability and moisture management.
Sea to Summit liners are treated with HeiQ Fresh FFL, a highly effective, biocide-free odor control technology that uses a bio-based amino sugar polymer to neutralize body odors.
