Description

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.

The only issue is that is very fragile. I was holding it and it hit the fence while I was walking and it got a dent. You have to look after it a lot.!

  • Nice looking
  • Breathable

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
