Outstanding clarity, peripheral vision and comfort have been the hallmark of our entire line since the late 1940's when we invented the first skydiving goggle. Today Kroop's brand is still the most widely used Skydiving goggle in the world. The Tropos Arch goggle features a patent pending soft elastomer frame that provides a comfortable, cool, and dry fit on any face size or shape. The lenses are interchangeable to a wide variety of other colors and features designed specifically the unique conditions of sky diving. All are 100% UV Blocking and impact resistant. This goggle comes with its own ballistic nylon carrying case.
