Product details
Description
The Green Flash Fast Lanes are seriously slick. The front frame’s jelly colors fade from emerald at the bottom to deep-sea green up top. This deep-sea green continues as the interior base of the arms, while the exteriors resemble something you'd see out your car window while cruising the PCH during golden hour. And like little sunset splashes, a speckled layer of gold and light blue provide a backdrop for the palm tree lined arms. Shimmering gold lenses and gold K logos round out these cool, yet laid back pair of shades.
Designed on one of our most popular frame styles, the Fast Lanes feature clean-cut, rectangular lenses, and provide full UV400 sun protection. Every pair comes with a co-branded Green Flash x Knockaround protective, sunset palm pouch.

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!
