Sea to Summit Reactor Extr. Sleep.Bag Liner Mummy w/Drawcord- C spicy orange

Thermolite® Pro insulation with infrared-reflecting technology for serious cold-weather sleep system extension.

The Sea to Summit Reactor Extreme Mummy Liner is designed to extend the warmth rating of a sleeping bag in cold conditions. Built from Thermolite® Pro — a hollow-core synthetic with infrared-absorbing ceramic pigments — it reflects body heat back to the user rather than letting it dissipate. The stretch-knit construction accommodates mummy bags of any shape, and adjustable openings allow it to function as a standalone liner around camp.
