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.

Polar Plunge Blurb Image

Polar Plunge

Dare the depths of winter with the Polar Plunge Fast Lanes, where every shimmer of ice and sparkle of snow transforms the world into a crystal palace. These sunglasses are your portal to the frost-bitten wonderlands where the air is crisp and the skies a clear winter blue. As adventurers brave the icy waters in a ceremonial plunge, these lenses guard not just against the sun's glare but the enigmatic allure of the polar realms. Venture forth, feel the chill as a whisper of the wild, and let every snowflake tell its tale. With Polar Plunge Fast Lanes, the spirit of winter is not just seen—it's felt.

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!

Another great styling by KA!

The transparent frame on these is really cool (pun intended)! Had my eye on them for a while and saw they were going away so had to pull the trigger!

So pretty!

I think this might be my favorite colorway!

The crystalline look, and the colors combine to give an icy look, which works for both summer (when we wish we’re cool temp-wise), and winter (when it’s icy out).

I also like that the cloth bag is designed to match, and not just one of the standard solid color ones.

My only complaint, and it’s a minor one, is that there’s reflection on the inside on the lenses. I mostly notice it when I’m not focused on driving, or something else that guides my gaze outwards, so I don’t focus on the slight reflection of my face to the sides of the inside of the lenses.

As I said, it’s a minor complaint, and I’ve still been wearing them every time I go outside since I got them, because I do really love everything else about them!

Awesome

The Polar Plunge sunglasses are hands down my favorite pair I’ve owned. The icy blue frame and mirrored lenses are not only stylish but also super unique—I’ve gotten compliments every time I wear them. They’re lightweight, comfortable for all-day wear, and the fit is perfect—not too tight, not too loose.

The lenses do a fantastic job of cutting glare and protecting my eyes in bright sunlight, especially near the water. Whether I’m at the beach, hiking, or just driving, these shades are my go-to. The quality feels premium and they’ve held up great through lots of use.

If you’re looking for something bold, functional, and fun, you won’t go wrong with Polar Plunge. Highly recommend!
