| Colour | Black Series |
| Suitable for | Everyone |
A midweight layer that unlocks year-round thermoregulation with adaptable layering, updated with a simplified structure to unlock universal utility - one textile, one zipper, total versatility.
Midweight insulation can provide year-round comfort - if it's engineered correctly. For cool conditions or long alpine descents in the summer, the ThermoBooster P1 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.
