At ESS, our unyielding passion is to make the toughest eyewear in the world. Not because it's our job, but because it's our duty -- a duty inspired by those we serve: military personnel, first responders, and other everyday heroes. Those who rely on ESS can't settle for less, so we can't either. We provide go-to styling and superior fit, form, and function so our tough customers can stay safe and be brave: on or off duty, beyond risk and on to adventure. ESS innovation is born from intense listening to elite warriors. We dissect their challenges, then roll up our sleeves to create real-life solutions that work under duress. The end result is battle-proven eye pro with a track record of peak performance in the most hostile environments. The entire line of ESS ballistic-grade eye pro is engineered to meet or exceed the most stringent U.S. Military and ANSI Z87.1-2010 specifications.
