Spatzwear Windsock PRO Aero Oversock – Black

The Spatzwear Windsock PRO is a race-ready aero oversock engineered to push performance beyond the already proven Windsock2 platform. Worn to victory in Tour de France stages, major Classics, and the UCI World Gravel Championships — and used by Mathieu van der Poel at Omloop Het Nieuwsblad 2026 — the Windsock PRO is the choice of the world's fastest riders. Available here in a sleek, versatile Black colourway.

Wind Tunnel Tested Aerodynamics

Developed for maximum efficiency in fast race conditions, the Windsock PRO was tested at the SSE Wind Tunnel Hub, delivering consistent CdA reductions over the standard Windsock across most yaw and speed angles. Every detail — from the aerodynamic lycra leg section to the striated ankle fabric — is shaped to reduce drag and keep you faster for longer.

Waterproof, Secure & Built to Race

A waterproof stretch main panel protects against wind and the elements, while the super aerodynamic lycra leg section delivers a close, stable fit. The newly developed internal gripper system ensures the oversock stays exactly where it should, lap after lap.
