The Gunner merges fashion with functionality by combining the most desired aspects and features of any eyewear available. The wrap-around Grilamid TR90 frame can be worn either with smooth temples as a sunglass or with a detachable, adjustable strap as a goggle. Vented removable closed cell foam prevents lens fogging and keeps wind and debris from distorting vision. Photochromic lenses that change with altering light allow for greater clarity and for night the Gunner also comes with a clear set of lenses. *Please note that while these glasses would presumably pass ANSI Z87.1-2010 standards, they are NOT certified, and are therefore not endorsed as safety eyewear by Safety Glasses USA.
