With its incredibly insulating 110g/m2 Thermolite fabric, the Thermolite Reactor Extreme boosts sleeping bag performance by up to 15 degrees Celsius. In order to save weight, improve thermal efficiency, and provide a good night’s sleep even when the temperature drops, the roomy shape is slightly tapered from head to foot. Additionally, the Reactor has a drawcord-adjustable hood that can be pulled down as needed for added warmth.

Thermolite is a hollow-core fabric that offers exceptional warmth for its weight while being incredibly breathable. When used alone as a warm weather bag or to supplement a sleeping bag, the Thermolite Reactor Extreme is perfect.
