Designed with influence from Team Sky, the Kask Protone Road Helmet is incredibly aerodynamic, lightweight, ventilated and proven at the sports highest level. 

The Protone has been tested in the wind tunnel and sculpted to perform. This ensures that it has an impressive coefficient drag rate, and any position that your head is put in will allow the air to flow perfectly in line with the helmet. 

It features a rubberised micro dial on the back called Octofit to provide optimum fit, with floating contact points and internal gel pads for comfort. The fit system is designed to move freely all the way to 180° to fit perfectly on any shaped head. All of this has been developed with weight in mind and helps the Medium weigh just 215g and Large just 250g.

Other impressive features of the Protone include:

  • Eco Chinstrap – An eco-leather, anallergic and washable chinstrap that’s extremely comfortable and helps to avoid skin irritation
  • 3D Dry – Tri-dimensional padding with a multi-layer open cell construction process, this for the best comfort and performance
  • Coolmax Padding - Removable and washable Coolmax inner padding
  • M in-moulding – This joins the inner polystyrene layer to the outer polycarbonate layer and ensures better shock absorption
  • MIT Technology - MIT guarantees complete protection thanks to the polycarbonate layer that covers the shell on the top, on the base ring and on the back
  • Sanitised inner padding fabric treated with antibacterial and antimicrobial for
  • High visibility stickers for maximum safety even in poor visibility conditions
