The Alpina MYTHOS REFLECTIVE cycling helmet comes with an extremely reflective foil on the bottom of the helmet to maximise safety in low light conditions. The top plastic shell is made of polycarbonate, which is also used as a foil for bulletproof windows. The helmet is well ventilated with 25 ventilation holes, and the front part of the helmet has a protective insect net. Size adjustment is provided with the new "Run System Ergo +", which can be operated very comfortably even while riding with only one hand, and the new "Swing Fit System", which allows you to adjust 3 different angles of the adjustment mechanism according to the size and shape of the nape.
