DESCRIPTION
Midweight insulation can provide year-round comfort – if it’s engineered correctly. The ThermoBooster P1 is. For cool conditions or long alpine descents in the summer, it layers over a standard jersey for additional warmth. In wet conditions, it insulates the microclimate beneath a rain shell. For extremely cold and wet conditions, it layers beneath a winter jacket for thermoregulation equal to the deepest winter conditions.
