10 Ventilation Ports
Proper ventilation is more important in a snowmobile helmet, than perhaps any other motorsport. 509 helmets include 5 intake vent ports (three in the mouth piece area, two above the eye port) and 5 exhaust port (2 along the bottom, 2 in the middle, 2 along the top). This 10 piece ventilation system provides a continual flow of cool air, providing a constant comfortable temperature while riding. This system keeps you comfortable by continually exhausting any built up warm air through the rear exhaust ports. This also helps prevent goggle fogging.
Wind Guard
The 509 Evolution helmet comes standard with a built in flexible rubber wind guard. This sleek guard provides an added level of wind protection. In combination with a set of 509 goggles, this wind guard overlaps the goggle's nosemask, providing a double layer of wind stopping protection. No longer will freezing wind reach your cheeks or nose area.

Washable Liner & Cheek Pads
All 509 helmets include a removable snap liner & cheek pads. The liner is made of a triangle tricot brushed material that is hypo-allergenic. The entire liner and both cheek pads are built onto the snap in system which allows you to easily remove them for washing.
Tool-less Visor Screws
The visor is attached to the helmet using a oversized tool-less triple screw setup. These large rubber coated screws are completely adjustable without any tools. Their design allows for quick adjustment even with bulky gloves on.
