SEA TO SUMMIT Thermolite Reactor Extreme Long - sleeping bag liner

Thermolite® knitted liner of pliable construction. These fibers increase the thermal comfort of sleeping bags depending on the environmental conditions and the physical condition of the individual.

Available in four variants: the Reactor, Reactor Compact, Reactor Extreme and Reactor Fleece Liner with different material weights and different thermal comfort enhancements.

Sleeping bag liner made of Thermolit® fibre increasing thermal comfort by up to 15°C (depending on ambient conditions, physical condition of the sleeper, etc.). Thermolite® is a hollow fiber that provides high thermal comfort for its weight while remaining extremely breathable. The weight of the material is 110g/m2.

Reactor Extreme uses our super insulated Reactor Extreme 110g/m3 material to significantly increase the performance of the sleeping bag. The generous cut allows for comfortable sleeping conditions. With its conical design, the Recator Extreme has excellent thermal efficiency and is lightweight. The hood with drawstring can be pulled together for maximum warmth if required. The built-in stretch makes the Reactor Extreme the ideal liner for those who move around a lot while sleeping.
