The Reactor Extreme uses our super insulating 110g/m² Thermolite fabric to seriously increase sleeping bag performance. The spacious design is slightly tapered from head to foot to reduce weight and increase thermal efficiency, and the drawcord hood can be cinched down for extra warmth when required. This knit fabric also has serious stretch to it.
