The Vertex 1.5 Plate Carrier and Operating System. The Vertex Operating System has undergone three years of quiet development, iteration, and field testing, made better by lessons learned and user feedback received on V1. Redefining the boundaries of lightweight, scalable, maritime-ready plate carriers, the Vertex is what you make it – literally. Made from water-resistant 500D Cordura laminate, the Vertex can adjust to any S​/​M plate variant using Velcro OneWrap adjustment tabs and a FIRSTSPEAR 6​/​12® plate backer (L​/​XL coming soon). The Vertex can augment existing S​/​M slick plate carriers for increased capability and collapses for packing in a rucksack, duffel bag, or cargo pocket. Ballistic plates are top-loaded into the Front and Rear panels of the Vertex, and the reinforced bottom ensures plate security during wear. An open design encourages immediate drainage during maritime and over-the-beach operations. The Vertex also features native wire routing beneath the carrier’s surface, sewn-in shock cord lashing points and mounting options for PTTs, and integrated, removable FIRSTSPEAR TUBES® Buckles for mounting third-party cummerbunds. The Vertx is shipped with AXL Equinox rigid cummerbund and training plates
