Boost your sleep system’s warmth with the Reactor Fleeceweight. Thermolite hollow-core fibers and grid fleece trap and reflect body heat, adding up to 8°C|14°F with minimal weight. The stretch fleece and arm openings allow freedom of movement, while snap attachments fit Sea to Summit sleeping bags for easy access.
