Sesafety Class 3 Hi-Vis Quarter-Zip Sweatshirt — Fluorescent Yellow

The Sesafety Class 3 hi-vis quarter-zip sweatshirt in fluorescent yellow-green is an ANSI/ISEA 107-2020 Type R Class 3 garment with 1,240+ square inches of fluorescent background and 310+ square inches of retroreflective material — the maximum ANSI visibility class.

Why this hi-vis quarter-zip sweatshirt suits layered work

Not every shift calls for a full hoodie. The quarter-zip gives you the same top-tier Class 3 visibility in a trimmer top: a fluorescent yellow-green body with 310+ square inches of retroreflective material, and a short collar zip that slips over your head and opens to vent heat. The lime color reads with maximum daylight contrast against dirt, asphalt, and greenery, and the light build layers cleanly over a base without the bulk of a hood. Where a hooded sweatshirt can feel heavy in mild weather or catch on machinery, the quarter-zip stays trim and out of the way while still meeting the top visibility class. That makes it an easy everyday layer for crews who want to be seen without adding weight. As hi-vis tops go, this is the lightweight Class 3 layer, and the best hi-vis sweatshirts guide and ANSI/ISEA 107 guide explain how the classes and colors are set. It is visibility without the extra weight.
