Sustainability

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

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!

4ocean plastic neutral commitment

Committed to Sustainability

Knockaround is Plastic Neutral

Making high-quality shades is the core of what we do, but inevitably that means we contribute to excess plastic byproduct. The idea of being a net drain on the environment doesn’t sit well with us, so we partnered with 4ocean to maintain plastic neutrality and work further to improve the environmental friendliness of our process.

Great glasses!

This is the third time we have purchased these glasses - my husband has them in black and blue (x2 - there was an incident and that pair no longer works correctly). He has a fairly large head and we struggle to find sunglasses that don't pinch his temples and that he likes the way they look. These fit the bill! Knockarounds are a great pair of sunglasses!

Solid Pair of Shades

Really liked the shade of blue and the ombre effect. Wore them this weekend and they stay put on my face. Not so much when I put them up on my head
