Discover unmatched performance with our new compact and lightweight cycling helmet!
The Sigma-II features a revolutionary magnetic lens attachment system, allowing you to quickly and effortlessly mount and remove a wrap-around visor. This innovative design makes it easy to store the visor in the "flipped up" position, making it ideal for quick transitions in triathlons.
The hidden magnetic receivers on the helmet are fully compatible with SKY or A2 lenses, specially developed for our Omega and Alpha Aero helmets. For added versatility, an integrated visor can be purchased separately for athletes who don’t yet have a helmet with a visor.
