All specifications
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.

Lara 17 March, 2016

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
Ashley 29 February, 2016

Good but only if it fits

Purchased a medium which was fractionally too small and then the large is huge - think Mario Cart mushroom head. Build, durability and weight all brilliant.

Pros
  • straps feel great
  • low weight
  • internal padding
Cons
  • mushroom
Adam 25 January, 2016

Great helmet with quality details

Usually I am a Large in most helmets but with the Kask I fitted the Medium thanks to the clever adjustment system. The straps and clips are great quality and the helmet fits over and around the head as opposed to just feeling as though it is perched on top.

Pros
  • Great Fit
  • Great Shape
Cons
  • Bit pricier than some
