Why the Ergodyne GloWear 8320Z brings mesh comfort to Class 3

Class 3 is mandatory in high-speed zones — but a worker who is overheating in a solid-fabric vest is the worker most likely to take it off, and that is a compliance failure where visibility is critical. The 8320Z answers that with an open-mesh fabric that lets air move through the vest body to cut heat buildup, a zipper front for secure retention, and the full Type R Class 3 coverage of 1,240 square inches. It is the mesh counterpart to the standard woven 8330Z. As Class 3 vests go, this is the breathable zipper pick, and the best hi-vis safety vests guide and ANSI 107 guide cover how to match a vest to the work zone. It keeps Class 3 crews cooler and on-compliance.

What the Ergodyne GloWear 8320Z listing documents

From the published specs: ANSI/ISEA 107 Type R, Class 3 certification; an open-mesh fabric body for air circulation; a zipper front closure for secure retention; and the same Class 3 compliance as the standard woven 8330Z (1,240 square inches combined). These are true class 3 mesh vest credentials and a genuine zipper hi-vis vest — a breathable class 3 vest for hot-weather high-speed work.
