fast, light and perfect for everyday use and long hours in the saddle. Amazingly aero, you can feel the wind glancing off as you cut through the air. I've ridden multiple long distance rides in this helmet and you can hardly tell you are wearing it even in very hot conditions. Also Great colors to match any kit.

I used this helmet on my 24hr TT, it's incredibly comfortable and despite the looks very effecient at cooling (tested at 36 dgrees in the Alps and was still great), great stability too, highly recommended

After having used top of the range offerings from Giro, Bell and even Kask's vertigo flagship 1 & 2 models over the last 10 years the Kask Protone is quite simply the best looking and most comfortable lid I've ever owned. Pros Unbelievable fit/comfort Semi aero looks yet maintaining cooling vents Quality finish with leather chinstrap Lightweight and less bulky than the Vertigo. Cons Price. Try it then buy it!

Without doubt this is the most comfortable helmet I've ever used. Its very light, and you barely notice you're wearing it. The straps have a soft leather cover to stop it chafing on hot days, and the ventilation system is perfect for the British weather. And of course it looks great too!

Lightweight and aero - you hardly know it's there. Very secure round the back of the head with easy adjusting and very well ventilated. Wouldn't wear anything else

Kask Protone Road Helmet

230 gr. M Size (CE EN 1078)

CE EN 1078  - CPSC 1203  - AS/NZS 2063

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.
