The Resolve is a slim, lightweight frame with interchangeable lenses that can withstand the impact requirements of ANSI Z87 testing. The interior of the frame is lined with closed cell foam and both anti-fog smoked and clear polycarbonate lenses. A retainer strap is included and attaches to the tips of the temples to ensure eyewear remains secure. All pieces fit into the slim MOLLE carry case provided. Bezeld lenses for RX usage are available for purchase separately.
