Reactor letvægtssoveliner med Thermolite Pro

Every gram counts on an ultralight trip, and the Reactor Lightweight earns its place in the pack. Thermolite Pro fabric uses hollow-core fibers and infrared-absorbing ceramic pigments to trap body heat, adding up to 4°C|7°F of warmth without much bulk.

Stretch-knit construction and shaped arm openings let you roll over and reach out without fighting the fabric. A fitted hood keeps your head warm, and the stretch means the liner fits any sleeping bag shape you own.

HeiQ Fresh odor control keeps it fresher between washes, and it dries quickly. Snap connectors at the shoulders pair it with Sea to Summit sleeping bags. Machine washable, too — which means less washing for your bag.
