Description

If you’re a fan of Fast Lanes, you’re probably keen to the fact that they kick eyewear into high gear in almost every category.

And, like every pair of Knockarounds, these black-on-black sunglasses are exceptional in the high-quality category. They feature durable, impact-resistant, polarized lenses and come with a protective pouch, so they’re always in great shape when you need to rev up!

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.

Simple, effective, just what I needed.

Glasses look and feel great. Multiple compliments. I usually never ever wear sunglasses but after seeing these for the price that they were I couldn’t resist.

My third pair

I keep purchasing these, not because I am breaking them but because I keep losing them. They are by far the best and most versatile design I've ever purchased. Will start buying in bulk.
