The Cádomotus Sigma helmet is brand new for 2020. This is an ultra-light, high-end bike and skate helmet at a price point you wouldn’t expect.

The Sigma follows the latest trends in helmet design; with a robust shape, aerodynamic geometry and large ventilation channels that keep your head cool, even in the highest temperatures. This helmet is so light and comfortable, you might even forget you are wearing one... 

A Dial-Ratchet Lock provides a secure fit and is easy to adjust. But most important, besides being aerodynamic, comfortable and extremely light, this helmet will keep you safe on the road.

The Sigma helmet is available in two sizes and two colour schemes: matte black with a grey back, and matte white with a grey back. Approved for racing by UCI cycling, World Skate (FIRS) and ITU triathlon.
