This is a comfortable, secure fitting goggle lined with HydroX® foam that seals out dirt, dust and grime and ensures a comfortable fit. A ventilation visor works in tandem to allow breathability and manage perspiration. The clear Lexan lens is optically engineered to screen out 100% of harmful UVA rays, and the state-of-the-art ergonomic flex frame adjusts itself to each unique facial contour. A silicone-lined strap eliminates slippage. The Optical version has a larger inner volume designed to fit over prescription glasses. Black or Red.
