The Thermolite® Reactor Extreme increases sleeping bag performance by up to 15 degrees Celsius with its super insulating 110g/m² Thermolite® fabric. The spacious design is slightly tapered from head to foot to reduce weight and increase thermal efficiency and well as allows for a comfortable night’s sleep, even when the mercury plummets. The Reactor is also fitted with a drawcord hood to cinch down for extra warmth as required.
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.
