Tennis balls are meant to stand out, and so are the Backcourt Premiums Sport. The front frames are frosted tennis-ball-yellow, and each arm displays a mid-match scene, complete with net, ball, lines, and court. Polarized hardcourt blue lenses, green embedded rubber nose pads, and optic yellow K-logos will have you feeling like you’re rallying with Serena herself.
Designed on our best-selling frame style, the Premiums Sport are form-fitting, universally flattering, provide full UV400 sun protection, and feature embedded rubber nose pads to reduce slip, slide, and bounce. Every pair comes with a hardcourt protective soft case and a holographic numbered edition card.
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.
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.

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!
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!
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.
