ESS Crossbow Lens

A pair of extra lenses for the ESS Crossbow series.

Made of 2,4 mm thick polycarbonate. The manufacturer promises these are totally fog-free, but we would take this with a pinch of salt. However, the coating does seem to be very good. The outside is scratch-resistant. Both lense pairs are distortion-free with 100% UVA/UVB protection. The glasses meet or exceed the following standards:

• U.S. Federal OSHA
• ANSI Z87.1+
• MIL-PRF-31013
• EN 166

These are on the U.S. Army's Authorized Protective Eyewear List.
