Type O Class 1 Vest

A type O or Class 1 vest usually refers to a general-purpose vest that provides basic visibility and is suitable for daytime use. They provide the lowest level of added visbility required by ANSI/ISEA and sometimes come with reflective tape suitable for workers in low risk areas like warehouse, parking lots, amusement parks, marathons, or any location/event where traveling speeds are less the 25 mph.
