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.

One very comfortable helmet.

Looks, good, feels very comfortable, it seems to be slightly less noisy than the Mojito and I’m very happy. Can’t fault Mantel, they dispatched it almost immediately.

Pros

  • Comfort
  • Looks
  • Air flow

Italian style

Kask Protone is the best road helmet you can buy. Great price from Mantel.

Anthony, 13 March 2019

Great fit and look

The Protone is a nice looking, lightweight helmet. I’m a 59cm head size and I ordered the medium initially and although it just about fit it was a little snug on the forehead. No room to wear a cap underneath. Returned for a large and the fit is perfect. The large obviously looks bigger than the medium but not a huge mushroom. Looks pro in white with white Jawbreakers. Great helmet. Best price online from Mantel.

Pros

  • Design, looks, lightweight, adjustment
