Magpul Ascent Eyewear Polarized, Scratch Resistant Gray Red Mirror Lens with Black Wraparound Frame for Adults Designed to keep up with the most active user, the Magpul Ascent provides high-performance eye protection and all-day comfort while you're on the move. With a frame constructed of TR90NZZ and impact-resistant oleophobic lenses, the Ascent has our highest Z87+ ballistic rating. Its lightweight design provides rugged ballistic protection that ensures consistent overall protective coverage. Its tight, eight-base wrap keeps debris out, provides lateral eye and temple protection, and minimizes incoming stray light. The low-profile temples, combined with its over-molded temple and nose pads, keep the Ascent in place and comfortable all day long, even during high tempo and physically demanding activities.
