Get superior over-the-glasses eye protection. The overall design and silicone-body construction of Flex Seal over-the-glasses goggles offer exceptional advantages over other OTG options when it comes to getting a fully sealed fit with temperature adaptability and all-day wearing comfort. The soft, lightweight, cured silicone body conforms to almost any facial profile and provides an exceptionally snug seal to provide reliable eye protection that you can rely upon, even under extreme-temperature conditions. Once workers experience these googles, they may never want to wear anything else. Clear, polycarbonate lens features a proprietary HydroShield® Anti-Fog/Anti-Scratch coating to deliver consistent condensation-free performance for much longer than average, as much as 90-times longer than the majority of anti-fog treatments on the market, while providing excellent scratch-resistance, up to twice as effective as most anti-scratch treatment alternatives. Goggles fit snugly and comfortably over most prescription eyewear, and the adjustable, elastic-neoprene headband helps the wearer tailor the fit to their individual needs.
