Flamingo Eye Technology - Polarized lenses enhance the colors on the course so you can see your ball as you sink your hole in one (or go OB...) No Slip - We use enhanced silicone inserts with special grip coating to help eliminate slippage when sinking that flamingo putt. No Bounce - Our frame is snug and lightweight with a comfortable fit to prevent bouncing while you’re swinging out of your shoes. Wider polariszed lenses provide more coverage, which also acts as a great disguise when you order your 13th John Daly after the beer cart staff has cut you off.
