Kask top road helmet - improved aerodynamics, bike goggles can be plugged in. The Protone is probably the most advanced helmet in the current KASK range. Technically innovative and with a unique look. Developed in collaboration with the successful Team Sky, the Protone cycling helmet sets standards in terms of ventilation, heat dissipation and aerodynamics. Thanks to the large openings, the contact surface with the head is greatly reduced. At the same time, an internal substructure holds the helmet together in the event of a fall. In-moulding construction: The innovative injection moulding technology, whereby the inner polystyrene GAP foam is bonded to the outer polycarbonate shell, providing better shock absorption. Multilayer Open Cell construction: Ensures greater safety and seamless protection thanks to 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: Rubberised micro-dial adjustment system for improved grip. Antibacterial ECO-Leather chin pad: Allergy-free and washable closure system that is extremely comfortable and avoids irritation of the skin. Note: Size corresponds to head circumference. Please measure beforehand. Area of use: road and MTB.
