The Invader is for the practical, yet style conscious person. The wrap around frame is made of flexible, durable Grilamid TR90 and the fleece lined open cell foam keeps the wind and debris out of your eyes. Continuous wearing of this piece of eyewear from day into night is due to the photochromic lenses, which adjust to UV light. The lenses are shatter-resistant polycarbonate and optically correct so there is no distortion. The Invader comes with a carry case and microfiber cleaning cloth.
