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:
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.
Covering shell edge
We found a method to stich a strip of fabric around the helmet shell edge. The result is beautiful!
Sidepieces and chin strap
Plastic-coated stainless steel wire sidepieces and micrometric chin strap.
