Features of KASK Protone Helmet

  • 3D Dry Padding: The tridimensional 3D DRY padding utilizes a multi-layer open cell construction process: high technology for the best comfort and performance
  • MIT: MIT Technology guarantees a higher head safety, with complete polystyrene protection thanks to the polycarbonate layer that covers the shell on the top, on the base ring, and on the back
  • Octo Fit: Rubberized Micro Dial adjuster provides improved finger grip. Floating cradle contact points combine internal gel pads for optimum comfort. These supports are designed to oscillate freely through 180 degrees allowing a perfect fit on any shaped head
  • Aero Control: Incredibly aerodynamic and top performing shell, tested in a wind tunnel and able to provide a really impressive CX rate. Any position the head will assume the outflow of the air will be perfectly in line with the helmet
  • Inner Frame: The innovative inner strengthening frame offers greater mechanical strength and a better compactness. In case of shock, it prevents the helmet from breaking into many pieces, allowing greater safety for every rider
  • Eco-Leather Chinstrap: Chin pad with a synthetic leather chinstrap. The hypoallergenic and washable chinstrap is extremely comfortable and helps to avoid skin irritation
  • Coolmax Fiber: Removable and washable inner padding in Coolmax material
  • High Visibility: High visibility stickers for maximum safety even in poor visibility conditions
  • Weight: 215g (M size)
  • Standards: CE EN 107

Product Info for KASK Protone Helmet

The KASK Protone Helmet features a sleek profile designed with the aid of computational fluid dynamics software to create a shape that retrains its efficiency in the wind through all head angles. The result is a helmet that's quiet and low-drag in any position on the bike.

For a highly personalized fit, Kask's Octo Fit retention system has a rubberized dial tension adjuster, plus vertical adjustability and movable rear cradles. The Coolmax lining has an antimicrobial treatment, and the chin strap is made from eco-leather that's washable along with being super soft to prevent irritation.

Available in multiple sizes and colorways. A helmet storage bag is also included. Made in Italy.
