Sandbar Fast Lanes
Perfect for sunset beach walks and early starts alike, our Sandbar Fast Lanes are just what the explorer ordered. Silver ‘K’ detailing gives a subtle nod to your favorite sunny destination, while glossy, transparent tan frames show you’re hip to today’s edgy trends. Even though form is a definite priority on these polarized shades, function certainly comes into play with UV400 protection and impact resistance (in case of any outdoorsy mishaps).

In 2022, Knockaroud officially became Plastic Neutral—for every pound of plastic we use, we remove one pound from the environment elsewhere. But that’s far from where our sustainability efforts end. We’ve also implemented minimalist, recycled packaging, eliminated single-use plastics, and included recycled materials in our products whenever possible. There’s always more progress to be made, but we’re committed to putting in the work.
Stay Glare Aware
Polarized lenses cut glare by filtering out horizontal light waves, like the ones that bounce off water or the road. Without this glare, you’re left with a more gentle view and reduced eye strain, not to mention crisper, cleaner details!
