The Smith Prophecy OTG Goggles are an excellent over-the-glasses style goggle that gives you lots of protection as well as the features for optimal clarity and a fog-free view. The Spherical, Carbonic-X lens provides you with a large field of vision, scratch resistance and durability with TLT optics which tapers the lens toward the sides eliminating distortion and increasing peripheral vision. To make the most of your vision two layer DriWix Face Foam ensures a super comfortable fit and a strong thermal barrier to maximize fog prevention while also wicking the sweat and moisture away from your face. To enhance the OTG experience, the Floating Frame Membrane eliminates eyeglass temple pressure so that you feel comfortable. Made in the USA.
