The JT Proshield shares the same design with the JT Proflex, the big difference being that it is made from a harder material, so it does not flex. The Proshield provides superior breathability, comfort, and customizability, as any of its parts can be swapped with Proflex parts. This goggle is a fantastic option for anyone who wants a great value mask that can be customized down the road. Additionally, the Proshield utilizes a thermal lens to help reduce fogging, and with its already fantastic breathability, fogging will not be an issue with this goggle system! Much like the Proflex, over the years there have been a plentiful amount of Proshields on the market including different colors and styles, including the ever-popular Highlighter Proshields! As there are new JT Proshields released, we will be stocking them as quick as possible, so be sure to check here first when more are expected!
