YENPK Dirt Bike/motorcycle/ski goggles give you total protection. They provide fully sealed visual protection and feature foam-padded padding for ultimate comfort. The headband is adjustable to fit the helmet. Special frame design, even if the glasses are placed on flat ground with the lens facing down, it will not make the lens directly touch the ground and scratch the surface of the lens. There is a slight space between the lens and the ground to protect the lens from scratches. Protect your eyes from any danger, so you can spend more time enjoying the fresh outdoor activities.
