Stephen of The Gear Locker got his hands on the Shooter and Suppressor versions of the ESS Crossbow series and here are excerpts... "Since we didn’t approach these as true airsoft safety goggles, I didn’t do my usual close range abuse of them. I suspect they would fair well, but having no way to prevent a BB from getting past the sides or bottom, we really DO NOT RECOMMEND these glasses for airsoft. ESS has a number of great offerings in that regard, please check them out.

Of course, the best lenses and frames won’t help if you can’t see through fog. I find it much tougher to fog up lenses with open sides, though sometimes this is possible with heavy exertion on humid day. With that in mind, I wore the original frames on a run one day with good results. The design allows airflow from below, and ESS’ “ClearZone” technology seems to be working as I didn’t get even the slight blurring at the upper corners I sometimes see.  Even an hour of heavy yard work on a hot day left no fogging, which is rare for me. I’ll continue to try it in other situations and see what happens.

Real steel practice and competition presents you with a variety of situations as for ear and eye pro. Having the ability to swap quickly and easily between lenses that provide good wrap and sight lines is a serious benefit. I’ve used a variety of protective lenses, from really cheap to pricey, and while the ESS Crossbows fall into the pricey area, there’s a good reason for that; they’re worth it!"
