What is the goggles roll offs?

Goggle roll offs are basically a roll of clear film packaged in a canister that looks like a roll of 48 mm photography film and can be advanced through a pull cord on the goggles. They are meant to instantly clear your vision when racing through the mud while keeping knicks and scratches off the lenses.

A roll holds up to 40 advances, which should be enough for   racing motocross.   If you are riding trails, you can pack additional rolls and change them out when necessary.

WHAT ARE POLARIZED LENSES?

Polarized lenses reduce glare — the bright, harsh light that bounces off water, snow, and cars. Light emitted from the sun travels at a vertical wavelength. When this wavelength hits a reflective object, the light bounces off horizontally, intensifying its brightness. Polarized lenses have a filter that blocks horizontal light and dramatically reduces that harsh glare.
