Sea to Summit Reactor Midweight Liner Long black

A thermal liner that meaningfully extends the range of any sleep system without replacing it.

The Sea to Summit Reactor Midweight Liner Long is a mummy-shaped liner built for solo use in cool to cold conditions. Thermolite® Pro fabric combines infrared-absorbing ceramic pigments with hollow-core fibers to trap and reflect body heat, adding up to 6°C to an existing sleeping bag. Stretch-knit construction and shaped arm openings allow natural movement, while snap connectors at the shoulders integrate directly with Sea to Summit sleeping bags.
