Excellent Ventilation
The ST#1820/1830-FZ helmet is unique for its superior ventilation and excellent sweat absorption abilities.
A total of 11 ventilation holes are situated in the front portion of the helmet permitting fresh air to pass through
the helmet and cool the user's head.
In addition, ventilation holes are located on the top of the helmet (ST#1820 = 6 holes / ST0183O = 3 holes)
and ventilation holes are situated at the back allowing heat to be released effectively.
(ST# 1820 = 5 holes / ST# 1830 = 6 holes)
In order to achieve this degree of ventilation, the helmet's original double layer structure was created.
The inner shell acts to protect the user from falling objects.
A further unque feature is the inside absorption liner which unlike other helmets is positioned away from the shell
to alow and heat or humidity within to be released easily and repidly.
