Lightweight & Aero

The Kask Protone Helmet's sleek profile was 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 features 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.


- Eco-Leather Chinstrap: Chin pad with a synthetic leather chinstrap. The hypoallergenic and washable chinstrap is extremely comfortable and helps to avoid skin irritation.
- 3D Dry Padding: The tridimensional 3D DRY padding utilizes a multi-layer open cell construction process: high technology for the best comfort and performance.
- Coolmax Fiber: Removable and washable inner padding in Coolmax material.
- 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.
- 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° allowing a perfect fit on any shaped head. The Skeletal Brackets of the cradle have been designed and refined to provide the best fit and support whilst being as light as possible.
- 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.
- High Visibility: High visibility stickers for maximum safety even in poor visibility conditions.
- 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.
- Weight: 215g (M size)
