KASK Valegro WG11 Helmet White
Developed in cooperation with Team INEOS, the KASK Valegro WG11 helmet is designed to offer the best comfort ventilation when climbing or riding in hot conditions.
The profile of the Valegro's polycarbonate shell has been tested and refined by KASK's engineers in conjunction with a wind-tunnel to get the best results in terms of thermo-cooling performance. The Valegro offers advanced ventilation and an impressive weight of just 180g (size small). This new design offers maximum cooling through 37 ventilation holes with new breathable and quick-dry padding. The 5mm layer of fast-wicking thermoformed tri-dimensional padding is antistatic, bacteriostatic, heat regulating and moisture transferring using Resistex Carbon. Alongside this cutting edge technology, the chin pad with eco-leather strap contributes to a helmet that's comfortable to wear, all day.
