The Story

Experience unparalleled performance with our new compact and lightweight cycling helmet!

 
The Sigma-II features a revolutionary magnetic lens attachment system, enabling quick and effortless attachment and removal of a wrap-around eye shield. This innovative design allows for easy storage of the lens in the "flipped up" position, making it ideal for fast transitions in triathlons.
Hidden magnetic receivers on the helmet are fully compatible with SKY or A2 lenses, developed specifically for our Omega and Alpha Aero helmets. For added versatility, an integrated visor can be purchased separately for athletes who do not yet own a helmet with a visor.
 

3 Reasons to Choose the Sigma-II Helmet

  1. Embrace the latest trends in helmet design with a robust, compact shape and aerodynamic geometry.
  2. Stay cool under pressure with extra-large ventilation channels, ensuring comfort even in the highest temperatures.
  3. Utilize a full-face aerodynamic visor, perfect for triathletes or cyclists who wear prescription eyeglasses.

The Sigma-II helmet is designed to fit seamlessly with our wrap-around SKY lenses. These high-quality visors are tapered to correct prism effects, providing a more accurate vision for your rides.
 
Rest assured, the Sigma-II helmet is approved for racing by UCI cycling, World Skate (FIRS), and ITU triathlon, making it a trusted choice for competitive athletes.
