Headbanger

For some people, amps that “just go to ten” won’t cut it. A guitar riff that doesn’t melt faces isn’t worth it. Drum solos that don’t shake the foundation of the venue don’t count as drum solos. If you rock the metalhead moniker proudly, put your hand in the air with two fingers up and jam along with us.

Because you’re a headbanger.

description

The Headbanger Fort Knocks are for everyone who knows that music rocks harder when the amps are all the way up. A deep black front frame wraps polarized red monochrome lenses, complete with a skull lens etch in the right-hand corner. Each arm features a black and red blotched base, but the main event is a “Sign of the Horns” hand grasping a wild bolt of lightning. Eruption red hardware rounds out this hardcore pair of shades—perfect for your next concert!

Designed on our durable and high-quality Fort Knocks frames, these sunglasses have a slightly wider fit than our other frame styles and provide full UV400 sun protection. Every pair comes with a red lightning microfiber protective pouch, guitar pick, and a numbered edition card.

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!

In The Wild

Headbanger

Knockaround Sunglasses and Forbes

“Knockaround sunglasses deliver a lot of value for a very reasonable price.”

Knockaround Sunglasses and GQ

“Buy five and don’t worry about if (or when) you lose a pair.”

Knockaround Sunglasses and Newsweek

“If you're looking for affordable sunglasses that you can wear without worrying, Knockaround is the answer.”

Knockaround Sunglasses and Men's Health

“The selection styles are massive and always changing. If that isn't enough, you can even customize your own frames.”

Who we are

Sun and San Diego

Born, raised, and bathed in San Diego sunshine, Knockaround is the original, affordable sunglasses brand. Since 2005 we’ve committed to making durable shades that are both practical and stylish. Our stellar customer service and ever-growing selection of high-quality eyewear have made us not just hometown favorites, but go-to’s across the globe!

Plastic Neutral

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.
