Knockaround
Knockaround was founded in San Diego in 2005 by Adam Moyer, on the premise that a good pair of sunglasses should not be something you are afraid to lose. Two decades on that is still the pitch, and it holds up.
The frames are injected polycarbonate, which is why they take abuse rather than snapping, and every lens blocks 100% of UVA and UVB. Polarized options run through most styles, and the Knockterra and Knockterra+ tiers add color enhancement for people who want more than a plain tint. Premiums, Fast Lanes, Fort Knocks and Torrey Pines are the shapes to start with.
