Cycling Racing Helmet Very Light and Aerodynamic
Light and Performance
PROTONE
With just 215g of weight, Protone has the lowest drag and the fastest heat dissipation coefficients compared to any other ventilated helmet. Thanks to several ventilation holes and a thick padding material, heat and moisture are dissipated very fast, improving comfort and performance without giving up on safety: the top area is reinforced with an internal plastic sub-structure that increases crash protection. Nineteen colors available.

description
The Protone weighs just 215g and uses a 3D Dry padding with a multi-layer open cell construction process to give a more comfortable ride. It has removable and washable inner padding, made from CoolMax® fabrics and its inner padding fabric has been treated using the Sanitized® antimicrobial process. KASK has also continued to use its Multi In-Moulding Technology to create a polycarbonate cover for the top, base ring and the back of the helmet’s shell. This is joined to the inner polystyrene cap via KASK’s In-Moulding Technology to improve the shell’s shock absorption. Its strengthened frame further reduces the risk of a shock breaking the shell.

Eco-leather chinstrap Chin pad with eco-leather chinstrap The anallergic and washable chinstrap is extremely comfortable and helps to avoid irritation of the skin.
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 a 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.
In moulding The innovative “in moulding” technology, joining the inner polystyrene cap to
the outer polycarbonate one, ensures a better shock absorption.
MIT The MIT Technology, applied to all KASK cycling helmets, guarantees a higher
safety and a complete protection thanks to the polycarbonate layer that covers the shell on the top, on the base ring and on the back.
Octo fit Rubberised 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.
Sanitized treated fabric Inner padding fabric treated with antibacterial and antimicrobial Sanitized® process.
Aero control Incredibly aerodynamic and top performing shell, tested in the 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
