Active Sport Series: Beauty meets beast is the only way to clearly define this line. We've meshed our virtually unbreakable TR-90, contoured sport frames, with a soothing, 8 Layer, impact resistant, polarized lens. This glare absorption series was customized specially for the sports enthusiast that likes to go hard. Select models offer neoprene nose pads and V-Wave� temple tips that are positioned to keep the frames secure and comfortable over long periods of time. Attach the included sunglass strap through T-Peg� docking and wear the product loose or tight depending on your activity.
