Description
Warmth For Any Occasion
The Assos Men's ThermoBooster Midlayer is 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 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.
Features:
- RX textile is a versatile Roubaix-style thermoregulator providing soft, midweight insulation with a highly elastic, low-volume structure ideal for layering.
- Streamlined regularFit and body-contoured shaping reduce seams to eliminate friction and improve comfort and layering.
- Raw Cut construction eliminates hems and ridges for clean lines, improved aerodynamics, and low-volume layering.
- 85% Polyamide, 15% Elastane
