The Knockaround Premiums Sport are the polarized sunglasses I stopped worrying about. They are light, they grip your face when you run, and losing or scratching a pair does not ruin your week. The optics are not the sharpest, but for an everyday active sunglass this is the honest sweet spot of value.
Why you should trust this review
I bought a couple of pairs of Knockaround Premiums Sport myself, online, because I am cursed: I lose or sit on sunglasses with grim reliability, and I refuse to keep feeling guilty about it. Knockaround did not provide these, did not contact me, and has no idea I exist. That independence matters here, because the whole pitch of these glasses is value, and value claims are exactly the kind of thing brands like to flatter.
I have worn expensive sport sunglasses before and lost most of them, so I know what I am giving up and what I am not. Everything below comes from carrying these through a full spring and summer of running, cycling, driving, and just living, not from a quick try-on.
How we evaluated
I wore them. That is genuinely the test for a daily driver sunglass, so I made sure the conditions were varied. I ran several times a week in them, took them on road cycling rides where wind and sweat are the real enemies, drove with them on long bright highway stretches, and wore them around water where polarization actually earns its keep. I paid attention to whether they stayed put during hard efforts, whether the lenses cut glare, and how the frame and coating held up over months of sweat and abuse.
I also compared them directly against a pricier pair I already owned so I could judge optical sharpness fairly rather than grading on a curve. The point was to see where the savings show and where they do not.
Polarized lenses that actually cut glare
The single best thing about these is that the polarization is real and effective, not a sticker. On the water and on wet pavement after rain, the glare reduction was genuinely useful, and driving into low sun felt noticeably easier than with cheap tinted glasses. For a sunglass at this level, getting proper polarization is the feature that makes them worth recommending rather than just tolerating.
Where they give a little back is outright optical sharpness. Held next to my more expensive pair, the Premiums Sport lenses are a hair softer at the edges and the contrast is slightly less crisp. In normal use I never noticed it, but if you are the kind of person who scrutinizes lens clarity, you will see the gap. It is the most honest trade in the whole product: you pay less, you give up a sliver of optical refinement.
Grip and fit during real activity
The rubberized frame is the unsung hero. During running and cycling, the arms and nose grip enough that the glasses simply stayed where I put them, even when I was dripping with sweat on a climb. I have owned smooth-frame sunglasses that crept down my nose every few minutes, and these never did that, which for an active sunglass is most of the battle.
They are also light enough that I forgot I had them on, which sounds trivial until you wear heavier frames for a two-hour ride and feel the pressure points. The combination of low weight and a frame that stays put is exactly what you want from something marketed for sport, and the Premiums Sport nails it.
Durability and the no-heartbreak factor
This is the category these glasses really win. Because they cost a fraction of premium sport eyewear, I genuinely stopped babying them. I tossed them in a bag, set them face-down on tables, and dropped them more than once, and the worst outcome was a minor scuff. When I inevitably scratch or lose a pair, there is no heartbreak, and that freedom changes how you live with a sunglass.
The one durability caveat I will flag honestly is the rubber coating. After a heavy season of salt, sweat, and sun, the rubberized finish can start to degrade and get tacky on a well-used pair. It is not a dealbreaker at this value, but it does mean these are not a buy-it-for-a-decade proposition. They are a buy-a-pair-or-two-and-relax proposition, which suits exactly the person they are made for.
Who should buy the Knockaround Premiums Sport?
Buy them if you want a genuinely polarized, sweat-proof active sunglass that you can run, ride, and drive in without anxiety. If you lose or destroy sunglasses regularly, the value here is liberating, and the grip and light weight make them better at actual sport than a lot of pricier lifestyle frames.
Skip them if you are an optics purist who wants the absolute sharpest lens, because premium glasses still beat these on clarity. Skip them too if you want a single pair to last many hard years, since the rubber coating will eventually show wear. These are made to be enjoyed and replaced, not preserved.
The verdict
After a season of running, riding, and general abuse, the Knockaround Premiums Sport earned their place as my low-stress daily sunglasses. The polarization is real, the rubberized frame stays locked on during hard efforts, and the low cost removes the constant fear of loss or damage that ruins more expensive eyewear. You trade a little optical sharpness and long-term coating durability for that freedom, and for an everyday active sunglass that is a trade I would make again. If you want capable polarized sport glasses you can actually relax about, these are the value pick I keep coming back to.
