Boost your sleep system’s warmth with the Reactor Fleeceweight. Thermolite hollow-core fibres 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. Easy to clean and quick-drying, it features HeiQ Fresh odour control. Using a liner reduces sleeping bag washes, helping preserve loft and extend lifespan.
