The Dye i4 White Paintball Goggle has a revolutionary patent pending rapid lens changing system that allows you to change lenses in under 10 seconds. It is the quickest and easiest lens changing system in the sport today. The unique design of two tabs allows you to remove the current lens and replace or clean it with ease. Simply push on each interior tab arm, slide them forward and the lens is free to be removed. Insert the new lens and pull both tabs back to securely lock the lens in place. No separate parts to take off, no extra pieces in your hand.
