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.

A great addition to my kit, if it's too hot at night you can use it on its own and increases the warmth of your existing sleeping system appreciably.

Good 3 season performance. Small and light for a mid weight liner. Keeps your expensive sleeping bags cleaner for longer. Adds a few degrees Celsius to bag temperature.
Delicate and rips easily. Overpriced for what it is, this is the same with everything that makes it into the lighter weight categories though - use less material in production and charge more for it. This is not a particularly technical product other than its weight and pack size
