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!

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.

Perfection

Knockarounds are my “go to” for sunglasses. I have a large head and the Fort Knocks is a perfect fit. They are high quality for a low price.

Perfect Summer Shades

Knockaround never disappoints, The Blue Obsidian is a perfect color. Looks great, the quality is every bit what you would get from those overpriced “ Designer “ sunglasses. Small business first all the time
