Aero, light and well ventilated the new Protone has it all and is offered in a variety of colors to suite every kit.
The Protone takes into account the riders’ posture and how they behave while riding, for example catering for the rider taking off their glasses and inserting them into the the helmet without increasing drag.”
The Protone is lightweight, hitting the scales at a claimed 210g, and Kask reckon that the Octo Fit adjustment system will fit any kind of head shape. It uses removable and washable inner padding, made from Coolmax fabrics which have an antimicrobial treatment.
