Mega is a combination of everything that is right about eye protection, truly distinguishing itself as a Brass Knuckle best-in-class solution. Try it on first for its extreme comfort, then see how Mega can adapt to your needs. With an application-specific interchangeable design, it quickly transitions from spectacle to dust goggle with the push of a button. Either wear with standard temples as a spectacle or an elastic head strap; for similar features see our Transformer. With the temples, simply adjust the length for a custom fit. Finally, Mega is the only Brass Knuckle dust goggle to feature our proprietary, best-in-class, N-FOG™ PLUS anti-fog coating. In the world of eye protection, this is as good as anti-fog protection gets. For more on what makes Mega special, watch the N-FOG PLUS video.
