Description

A sophisticated combination of retro and modern tastes, our Obsidian Fort Knocks sunglasses check all the boxes and then some.

Polarized smoke lenses also provide UV400 protection and impact resistance for any forays into unexpected fun. Catch some eyes with dark chrome accents on the front, and don’t forget to show off the fancy arm script to anyone in need of some style guidance.

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.

Rock Solid!

Formed in volcanic awesomeness and brought to your face by Knockaround for compliments galore! These shades personify a look that others often try to imitate but cannot duplicate! Perfect weight, fit, and form! The colorway is spot on for the name, and much more impressive in person. They go with pretty much any outfit, dressed up or dressed down, and the polarized lenses are a game changer. Do yourself a favor and get this pair, but good luck, they’re a popular model and sell out fast whenever they hit stock!
