Why the Ergodyne GloWear 8370 pairs top visibility with sweat management

Sustained labor in warm conditions asks two things of a hi-vis shirt at once: the highest visibility class, and fabric that manages sweat so the wearer stays comfortable across a full shift. The 8370 delivers both — all-lime performance moisture-wicking fabric that carries Type R Class 3 with 1,240 square inches of fluorescent background and 310 square inches of retroreflective tape across the front, back, and sleeves, while pulling perspiration away from the skin. It is the same performance fabric as the black-front 8371BK in a uniform all-lime configuration. As hi-vis shirts go, this is the all-lime performance Class 3 pick, and the best hi-vis shirts guide and ANSI 107 guide cover how to match garment to the work zone. It keeps crews maximally visible and comfortably dry.

These are true class 3 performance shirt credentials and a genuine all-lime performance hi-vis shirt — a comfortable moisture-wicking safety shirt for sustained warm-weather work.
