Assos Thermobooster Foil

The Essential Foundation: High-Intensity Warmth

The Thermobooster Foil is designed to be the foundational layer for your deepest winter rides. When layered beneath a jacket and jersey, its unique construction elevates your core temperature management, making below-freezing efforts feel manageable.

Technical Advantages for Thermal Efficiency:

• High-Density Insulation: Constructed from a thicker, more insulating yarn blend than standard baselayers, the Thermobooster creates a crucial layer of warm air next to the skin, drastically improving the thermal efficiency of your entire layering system.
• Active Moisture Management: Despite its warmth, the fabric is engineered to rapidly transfer sweat and moisture away from the skin. This prevents the clammy chill that follows hard efforts, ensuring your microclimate remains dry and stable.
• Zero Bulk: Designed to be a high-compression, second-skin fit, the Foil integrates seamlessly under your jersey and jacket without bunching or restricting movement.
• Seamless Integration: The construction prioritises minimal seams to eliminate friction points, guaranteeing long-distance comfort, which is non-negotiable during high-volume winter base miles.

The Thermobooster Foil is a critical investment in your winter consistency, providing the core warmth necessary to extend your ride time and effort.
