  • Kask Protone Road Cycling Helmet (Matte Finish-WG11)

    The Kask Protone Road Cycling Helmet has built an enviable reputation for comfort, smooth aerodynamics and excellent cooling. It also now passes the WG11 Safety Test, certifying it's outstanding protection against both direct and rotational impacts. 

    Aerodynamic performance, low weight, maximum ventilation, amazing looks

    A traditional aerodynamic helmet can be too warm but the vents on a standard road helmet can increase drag. The Protone Road Cycling Helmet (WG11) has a revolutionary design which combines the best of both worlds. Originally developed and extensively wind-tunnel tested together with Team Sky (Now Team INEOS), the Protone delivers professional performance in a sleek and stylish package.

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

    KASK has 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.

    WG11 Safety Test

    The Protone passes the stringent WG11 test. This focuses on protection from rotational impact forces, measuring rotational kinematics from both oblique and normal impacts. With this safety test passed, you can be sure the Protone has you covered should you be unfortunate enough to fall from your bike. 

    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 by 70% 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 adjustment required. After putting on the helmet and fastening the chin strap, the divider moves to fit comfortably around the earlobe. The ergonomic design means a great fit for all head shapes and sizes, guaranteeing freedom of movement and excellent ventilation.

    Kask Octo-Fit

    Rubberised Micro Dial adjuster provides an 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

    Chin pad with eco-leather chinstrap

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