Assos GT Ultraz Winter Booties EVO

The ASSOS GT Ultraz Winter Booties EVO are engineered for extreme cold-weather cycling, delivering maximum insulation and weather protection for riders who refuse to stay off the bike in harsh winter conditions. Built as part of ASSOS’ stormproof winter system, they provide a high-performance barrier against wind, cold, and wet environments.

At the core of the design is ASSOS’ dual-layer twinDeck textile construction, which combines multiple insulating layers to trap heat while maintaining controlled breathability. This advanced structure ensures consistent warmth during long winter rides without excessive bulk or restriction.

The Ultraz version enhances the standard GT Winter booties with additional protective layers, increasing thermal retention and strengthening defense against wind chill and precipitation. This makes them especially suited for deep-winter training and demanding outdoor conditions.

Designed for committed cyclists, the GT Ultraz Winter Booties EVO prioritize warmth, durability, and all-weather resilience, helping riders maintain comfort and performance even in the most challenging environments.
