The Protone is the ''do it all'' aero helmet of KASK. The Protone offers the optimal combination of aerodynamics and cooling. Thanks to its Octofit adjustment system and divider earband you can adjust your Protone easily, quickly, and precisely for a perfect fit. Because of its eco-leather strap it is is very comfortable and prevents irritation on 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 the stylish touring riders.

Kask wanted more input besides Team Sky's so they spent a great amount of time to data research, position analysis (how does a rider behave on a bike) and thermodynamic studies. For example: what is the best way to put away cycling glasses in the helmet without increasing drag.

Excellent helmet from top retail

Previously had a Kask Vertigo and that was great but the Protone is even better. The rear adjustment is particularly good and well thought out. More aero? don't have a wind tunnel but certainly feels like it is!

Pros
  • Good adjustment
  • Design
  • Aero
  • Colour options
Cons
  • None

perfect helmet for the new road season

Perfect helmet for long hair, as the thing at the back where we girls put our hair trough is adjustable. The helmet is really light,you don't even notice that you are wearing one. Although I really like the helmet, I think that it is pretty expensive!

Pros
  • good-looking
  • light
  • good ventilation
Cons
  • expensive
