The Pyramex XS-G Glasses come with interchangeable temples and head strap that allow quick conversion from safety glasses to protective goggles. The strap has a Quick Fit retainer for easy on/off. These Pyramex Safety Glasses exceed the ANSI Z87.1-2003 High Velocity Impact Standards, meet CE EN 166, and are Certified CAN/CSA Z94.3-07.
