Stay fog-free for hours at a time with your sports and winter weather activities with the Breakthrough Clean Technologies Anti-Fog Lens Gel Tube and Cloth Kit. The anti-fog gel effectively eliminates fogging on lenses, optics and safety goggles, and the no-mess brush applicator makes sure to not leave a mess behind. A tip lets you precisely apply the gel in a thin layer exactly where you want it, and the lens cloth gently wipes away the gel to give you a crystal-clear view.
