This is ANSI Class 3 Compliant with a 5pt Breakaway design. Made with lightweight, comfortable and durable 3.1oz Polyester Mesh, the safety vest has two inside pockets, one large outside pocket, cell phone & pen/pencil pockets, a mic tab and a breakaway zipper front closure. Our High Visibility Safety Vest features 1303 Reflective Material and contrasting fluorescent orange tape. The 5 point breakaway feature allows the garment to meet additional safety specs of road workers and heavy machinery operators. The non-locking zipper literally unzips itself with pressure - the hook and loop closures along the sleeves and side seams complete the breakaway.
