Our new performance cycling helmet is so compact, light & comfortable you forget you actually have one on!
The Sigma-II features our race-proven magnetic lens attachment system that allows for quick attaching and removal of a wrap-around eye shield. Our system allows easy storage of the lens in the "flipped up" position - perfect for fast transitions in triathlon.
The new 'hidden' magnetic receivers on the helmet are fully compatible with SKY or A2 lenses, that we developed for the Omega and Alpha Aero helmets. An integrated visor is an option that you can purchase separately, for those athletes who don't own an Alpha-2 or Omega helmet with a visor yet.
3 Reasons to wear a Cadomotus Sigma-II helmet
-
Sigma-II follows the latest trends in helmet design; with a robust compact shape and aerodynamic geometry.
-
Sigma-II keeps your head cool thanks to extra large ventilation channels, even in the highest temperatures
-
Sigma-II allows you to use a full-face aerodynamic visor, great for triathletes or cyclist wearing prescription eyeglasses
The Sigma-II helmet fits with our wrap-around SKY lenses. Higher quality visors like Cádomotus SKY lenses are tapered and corrects the prism effect for a more accurate vision.
