Why the Ergodyne GloWear 8371BK tops the shirt line

When a job demands the highest visibility class but a crew also wants a sharper look and summer-ready fabric, the 8371BK is the top of the GloWear shirt range. It meets Type R Class 3 — the 1,240-square-inch fluorescent-background and 310-square-inch retroreflective-tape minimum that makes a worker visible farther out and in lower light than Class 2 — while a black front reduces the all-lime profile and moisture-wicking fabric manages sweat during active work. As hi-vis shirts go, this is the top-tier performance pick, and the best hi-vis shirts guide and ANSI 107 guide cover how to match garment to the work zone. It gives maximum visibility with a professional edge.

What the Ergodyne GloWear 8371BK listing documents

From the published specs: ANSI/ISEA 107 Type R, Class 3 certification; performance moisture-wicking fabric; a black-front long-sleeve design; and the Class 3 minimums of 1,240 square inches of background and 310 square inches of retroreflective tape. These are true class 3 performance shirt credentials and a genuine black front hi-vis shirt — a top-tier ansi 107 class 3 shirt. The black front is styling, kept clear of the required visibility material.
