Sea to Summit Reactor Midweight Sleeping Bag Liner

Sea to Summit Reactor Fleeceweight Sleeping Bag Liner

The Reactor Midweight boosts your sleep system’s warmth using advanced Thermolite Pro fabric. Hollow-core fibres and infrared-absorbing ceramic pigments trap body heat, adding up to 6°C / 11°F with minimal bulk.

Stretch-knit construction and arm openings allow unrestricted movement, making it compatible with any sleeping bag shape. Quick-drying, easy to clean, and treated with HeiQ Fresh odour control, it also helps extend your sleeping bag’s lifespan by reducing the need for frequent washing.
