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.
