Cadomotus SIGMA-II COMPACT AERO GALAXY

Our new performance bike helmet is so compact, light and comfortable you'll forget you're wearing it!
The Sigma-II features our race-proven magnetic click system that allows for quick attachment and removal of a visor. Our system makes it easy to store the lens in the "up" position—perfect for quick swim-bike transitions in triathlons.

The new "hidden" magnets in the helmet are fully compatible with SKY or A2 lenses, which we developed for the Omega and Alpha Aero helmets. The integrated visor is an optional extra available for athletes who don't yet own an Alpha-2 or Omega helmet with a visor.

3 reasons to wear a Cadomotus Sigma-II helmet

Sigma-II follows the latest design trends in helmets, with a robust and compact shape and aerodynamic geometry.
2. Sigma-II keeps your head cool thanks to the extra large ventilation channels, even at the highest temperatures
3. With Sigma-II you can use an aerodynamic visor, perfect for triathlon or cyclists who wear glasses.

Our SKY lenses fit Sigma II helmets. Higher-quality visors, such as Cádomotus SKY lenses, are tapered and correct the prism effect for more precise vision.
