Product description

The Thermolite® Reactor Extreme increases sleeping bag performance by up to 15°C with its super insulating 110g/m² Thermolite® fabric. Spacious design allows for a comfortable night’s sleep, even when the mercury plummets. Thermolite® is a fibre with a hollow core that provides extraordinary warmth for its weight while remaining extremely breathable. The Thermolite® Reactor Extreme adds warmth to a sleeping bag or, used alone, is ideal as a warm weather bag. With the stretchy knit fabric that moves with you and a draw cord hood, this liner is perfect for wrigglers and rollers or anyone who needs some extra warmth.

Good liner for sleeping bag. Bone promises more than gives.

A good addition if you do not take a summer or talal bag and if you end up in a summer bag. Mieski Kehu, although not the basis for extra lattice stretchers.

Overall rating
A functional and handy inner bag for hiking, which allows you to take a thinner sleeping bag with you and adjust the sleeping temperature better, even if some of the nights are outside and some of them are in the living room.
