Casca CUBE Helmet Heron White When we set out to design the HERON, we didn't want to create just any road bike helmet. We wanted to create the ultimate road bike helmet! If you think aerodynamics come at the cost of an overheated head and painful neck – think again! After extensive wind tunnel testing, we came up with a design that directs cooling air over the entire head via deep ventilation channels yet doesn't look or feel too bulky in the process. It effortlessly comes in at below 250 g – super light for an aero helmet – meaning maximum comfort for an extra portion of speed even on long-distance rides. road helmet; MIPS; 9 large vents; SILC 180+ Fit System with height and width adjustment can be fine-tuned with one hand for a perfect fit; triple-in-mould construction; flat dividers for optimised webbing guiding; removable, washable and antibacterial pads; other pad thicknesses available; Natural Fit concept; matte brushed + glossy finish size S (49-55) - M (52-57) - L (57-62) material EPS triple-in-mould weight 265 g
