Product details

New Kask Top Road Helmet – Improved Aerodynamics, Compatible with Sunglasses

The Protone is arguably the most advanced helmet in the current KASK lineup. Technically innovative and featuring a unique design, it was developed in collaboration with the successful Team Sky, setting standards in ventilation, heat dissipation, and aerodynamics. The large openings significantly reduce the contact area with the head, while an internal substructure keeps the helmet intact in the event of a fall.

Details:

  • In-Moulding Construction: The innovative injection molding technology bonds the inner polystyrene GAP foam with the outer polycarbonate shell, providing better shock absorption.
  • Multilayer Open-Cell Construction: Ensures higher safety and seamless protection, thanks to the polycarbonate layer on the top shell, sides, and back.
  • 20 ventilation openings
  • 3D-Dry System: Antibacterial padding made of Coolmax material (removable and washable).
  • Headset with Octo-Fit System for optimal adjustability: Rubberized micro-dial adjustment system for improved grip.
  • Antibacterial ECO-Leather chin pad: Hypoallergenic and washable closure system that is extremely comfortable and prevents skin irritation.
  • Note: Size corresponds to head circumference. Please measure beforehand!
  • Intended use: Road and MTB
  • S = 50-56 cm, 205 g
  • M = 52–58 cm, 215 g
  • L = 59–62 cm, 250 g.
