KASK’s most advanced helmet to date, the Protone was developed in collaboration with Team Sky. It has among the fastest heat dissipations and lowest drag co-efficient of any ventilated helmet available.

Aerodynamic performance, low weight,maximum ventilation, amazing looks.
The Protone weighs just 230g 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.



Additionally, its Octo Fit adjustment system guarantees a perfect fit to any kind of head shape. 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.

3D Dry tri-dimensional padding

• • The special internal padding is based on an innovative multi-layer open cell construction process that gives maximum comfort and performance thanks to a series of technical features:

• • - Several ventilation holes that reduce the head-to-pad contact surface by70% compared to standard designs

• • - 5mm thick padding material that wicks moisture away from the head and moves it to the helmet’s outer shell – fast

• • - Excellent three-way evaporation Aerator position at the top of the helmet boosts safety

• • - The top area is reinforced with an internal plastic sub-structure that increases crash protection and helps maintain the helmet’s integrity after impact.

CoolMax® material padding

• • The front of the helmet features a highly effective sweat-absorber that is easily removable and washable.

Self-adjusting lateral divider

• • This provides great rider comfort with minimal adjusment required. After putting on the helmet and fastening the chinstrap, the divider moves to fit comfortably around the ear lobe. The ergonomic design means a great fit for all head shapes and sizes, guaranteeing freedom of movement and excellent ventilation.

Chin pad with eco-leather chinstrap

• • The anti-allergy, washable chinstrap is extremely comfortable and helps preventskin irritation. It incorporates soft lateral spacers, shaped to enable excellent ventilation and avoid that unpleasant ‘sweaty strap’ feeling.
