Kask Protone Icon

New Kask Top Road Helmet – improved aerodynamics, compatible with eyewear. The Protone is arguably the most advanced helmet in the current KASK lineup. Technically innovative and featuring a unique look. Developed in collaboration with the successful Team Sky, the Protone cycling helmet sets standards in ventilation, heat dissipation, and aerodynamics. Thanks to the large openings, the contact area with the head is significantly reduced. At the same time, an internal substructure keeps the helmet intact in the event of a fall. In-Moulding construction: The innovative injection molding technology, which bonds the inner polystyrene GAP foam with the outer polycarbonate shell, ensures better shock absorption. Multilayer Open-Cell construction: Provides 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 from 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.
