Kask Protone Road Helmet

Kask's new Protone helmet, developed in collaboration with Team Sky, is a highly adjustable, cool and comfortable class leading helmet. The Kask Protone  boasts impressive aerodynamics for a well-vented helmet too.

Some helmets feel like they perch on top of your head a bit like a flat cap,  The Kask Protone is the exact opposite. It feels like it fully encompasses your head, reaching low at both the front and, especially at the back of your head.

Kask's Octo Fit adjustment system is great and very simple to tweak. The arms of the cradle fasten to the inside of the helmet's expanded polystyrene body at your temples and again at the rear where you get a generous amount of height adjustment.

The tightness of the fit is adjusted via a dial system at the back and you can alter the sideways position of those occipital pads independently so they sit in the most comfortable place. The overall result is that you can get a secure fit in no time at all.          

One other feature that I really like is that the chinstrap isn't simply a continuation of the upper straps – a feature of other Kask helmets. Check out the pictures and you'll see what I mean. The result is that the straps always sit flat and there are no dividers to set underneath your ears. 

The chinstrap on the Kask Protone is made from eco leather and it's easy to wipe clean when you get it sweaty. The antibacterial and antimicrobial inner padding – removable for washing and replaceable if it wears out – is made from Coolmax and most of it has a honeycomb inner surface. Along with large ventilation holes at the front of the helmet, it helps keep your head feeling cool and well aired.

The Kask Protone Helmet has been designed using computational fluid dynamics software to have one of the lowest drag coefficients of any ventilated helmet – particularly important to the likes of Team Sky, obviously.

The helmet also allows you to take off your glasses and stow them on the helmet using the vents as anchor points without increasing the drag.

The kask Protone helmet is highly adjustable, cool and comfortable helmet that has impressive aerodynamics.


3D dry

The tridimensional 3D DRY padding utilizes a multi-layer open cell construction process: high technology for the best comfort and performance.               

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.   


Removable and washable inner padding in Coolmax® material               

ECO Chinstrap

Chin pad with eco-leather chinstrap. The anallergic and washable chinstrap is extremely comfortable and helps to avoid irritation of the skin               


In case of shock it avoids the break of the helmet into pieces               

M in moulding

The innovative “in moulding” technology, joining the inner polystyrene cap to the outer polycarbonate one, ensures a better shock absorption.               


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.               


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                     


Inner padding fabric treated with antibacterial and antimicrobial Sanitized® process.
