Product Information

Made from 80g Thermolite, a hollow core fiber that provides extraordinary warmth for its weight while remaining extremely breathable, the Reactor increases sleeping bag performance by up to 8°C (14°F). Ideal as part of a cold climate sleep system or as a standalone bag in warm weather, the Reactor is lighter and more packable than fleece liners of comparable warmth.

Unfortunately provided no additional warmth at all. So only served as a quite expensive sleeping bag liner.

Very compact liner. Easy way to stretch the temperature range of my sleeping bag. I like that the liner allowed me to move around in my sleeping bag whilst the bag stayed where is was.
