Reduced width of the helmet
The advantage of a reduced width of the helmet are evident: less weight and less resistance to te air.
The disadvantage: if there is only one dimension of the shell like in this helmet, the maximum size is XL (61 cm of head circumference).
Polycarbonate shell
The 3 mm thickness polycarbonate shell has the advantage to be very light but still very strong.
Polystyrene reinforced
The polystyrene inside is reinforced with one more layer of polycarbonate to achieve the hard penetration test of the E.N. 966 certification.
Airflow inside the helmet
Between the shell and the polystyrene there are 2 channels with their holes for the air flow.
You can open or close the entrance of the air into the helmet just with one hand and while you are flying
Sizes
3 sizes available, each with an adjustable sizing wheel for head circumferences from 53 to 61 cm:
S (53-56 cm = XS-S)
M (57-59 cm = M-L)
L (60-61 cm = L-XL)
The size of a helmet is always described by the inner circumference of the internal padding.
The size number therefore corresponds to the head circumference in centimetres.
Interchangeable Internal Padding
3 internal paddings are adapted to the 3 sizes determined by the wheel regulator situated in the back of the helmet. They can be replaced by larger or smaller padding pieces included the wheel regulator thus varying the helmet size.
You just choose your own size of ICARO tailored inner helmet lining for a safe, perfectly comfortable head fit. It can be changed in moments in case a different size is needed.
If the helmet is not a perfect fit Icaro will send a new padding free of charge independently from where you bought the helmet.
