The Diamond S aluminum vents are laser cut out of 6061 aircraft aluminum for maximum durability with a very open pattern for maximum airflow. Aluminum vents won't tear when riding through the trees and bushes. The vents on the clutch side have a fine mesh on the back of them so the snow won't pass through. Vents will be available with or without logos. Polaris pro will have PRO-RMK cut in it similar to the one on the sled. The Aluminum allows you to customize your vents such as polishing, painting or powder coating.
