description

What’s better than black-on-black with a little more black? These triple-duty Fort Knocks are equipped with matte black frames, polarized black smoke lenses, and gunmetal hardware for an undeniably cool design. Each pair features the classic Fort Knocks silhouette, which is known for its steadfast strength, style, and versatility. These shades are tough: they feature impact-resistant lenses, high-quality hidden spring hinges, and have a comfortable and accommodating fit—they are named after the United States Bullion Depository in Fort Knox, Kentucky after all.

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.

shipping & returns

We ship Monday to Friday from our warehouse here in San Diego, CA, with the exception of holidays. For most standard orders, shipping takes about 5-7 business days depending on your selected carrier method at checkout (please allow up to 12 days for custom shades). Get your order sooner with our priority mail, 2nd day air, or overnight domestic shipping options. Once your order has been handed off to the carrier, you’ll receive a shipping confirmation email with your tracking information.


We also offer easy, free returns within 30 days of purchase for most products, with the exception of Custom Shop, Limited Editions, promotional items, and international orders. Check out our Help Center’s FAQ on returns for more information.

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

Knockaround Sunglasses and Forbes

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.
