FLAK JACKET® Sport professionals demand nothing less than the best, and we’ve answered their challenge for decades. World-class athletes have driven us to create innovation after innovation, including interchangeable lens designs with unbeatable optical clarity. Flak Jacket® takes that to the next level with the latest in performance technology. The clarity of High Definition Optics® was just our starting point. We created a permanent Hydrophobic™ lens coating to repel water, skin oils and debris, so the best vision on earth stays crystal clear. When the sun fades or flares on athletes like freeride legend Wade Simmons, the interchangeable lens design lets them adapt. Two sizes of nose pads help them achieve a secure fit that optimizes comfort.
