Why the Ergodyne GloWear 8330Z is the standard Class 3 spec

When a DOT specification or project safety plan calls for a Class 3 vest in a high-speed work zone, the 8330Z is the conventional answer. It is GloWear's standard Class 3 two-tone zipper vest — lime background with silver retroreflective striping in the torso and shoulder band arrangement that meets Class 3's 1,240-square-inch total, in a familiar woven format with a zipper front for secure retention. The two-tone contrast reads as a human silhouette at distance and in low light. As Class 3 vests go, this is the standard two-tone pick, and the best hi-vis safety vests guide and ANSI 107 guide cover how to match a vest to the work zone. It is the config most Class 3 programs specify.
