The Protone is the ''do it all'' aero helmet by KASK. The Protone offers the optimal combination of aerodynamics and cooling. Thanks to its Octofit adjustment system and divider ear straps you can adjust your Protone easily, quickly, and precisely for a perfect fit. Its eco-leather strap is very comfortable and prevents irritation to the skin. This strap is washable just like the helmet pads. Thanks to these features the Protone is the helmet perfect for both competitive professionals and
stylish touring riders.

Kask didn't just trust on Team Sky's input alone, so they spent a great amount of time on data research, position analysis (how does a rider move on the bike) and thermodynamic studies. For example: what is the best way to put away cycling glasses in the helmet without increasing drag.

Quality

Looks and feels well made. Sure last a long time. Fingers crossed

Pros
  • Light
  • Leather chin strap
Yiannis, 14 August 2018

Great ventilation and comfy fit

I had the Rapido helmet before, which I liked a lot. Protone has much better ventilation, and is apparently (didn't measure it) more aero. Fit is better too, with more adjustment and better contact points.

Pros
  • fit
  • ventilation
Jimmy, 7 August 2018

Great fitting helmet

The fitting system of the Kask helmets seems to hug the head perfectly without any pressure points and is comfortable all day. Lots of vents to keep you cool and it looks great too ! The only thing I don't like is the fake leather chin strap....something lighter and more supply would be better.

Pros
  • comfort
  • lightweight
  • ventilation
Cons
  • Stiff chin strap

Great bit of kit...

The Protone is a great bit of essential kit. Have had a few different helmets (Synthe / S Works) and in my opinion this is the best looking and most comfortable to date. Loving the stealth looks and leather chin strap. Adjustable liner works really well and all important sunglasses storage slots don't let you down. Was not thinking about a new helmet but with the TOUR Deals it was too good a deal to be missed!

Pros
  • Looks
  • Comfort
Cons
  • Expensive

Excellent purchase

I've lusted after this for so long, finally being able to get it is a dream come true

3D Dry

Aero Control
This helmet is fitted with a wind-tunnel tested aerodynamic shell. Whichever way you’re looking, the air exhaust will always be able to do its work.

ECO Chinstrap
An anti-allergenic and washable chin strap with high levels of comfort. Helps prevent skin irritation.

M Moulding
