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.

Banffshire Enthusiast
It is very good at trapping body heat and material is soft and warm to touch.
Length is perfect for my 1.85m frame. Breathing is not impared when drawn over face.
Works well with my Hagloffs light 3 season bag for winter bothying in Scotland.
Light and packs into compression bag with my sleeping bag.
Maybe a bit expensive but it looks as if it will last forever.

Builth Wells Enthusiast
It kept me warm on a very damp wild camp inside my 2 season bag
Because the inside finish is 'brushed' it catches on the rough skin on my manky feet
