In plain words. ANSI/ISEA 107 sorts high-visibility garments by how much fluorescent background material and reflective tape they carry. Class 1 is the least, Class 2 is the mid level and Class 3 the most; Class E is for pants and bibs that only reach Class 3 when worn with a Class 2 or 3 top. The Type says where the garment is meant for: Type R for roadway and temporary traffic control, Type O for off-road work, Type P for public safety. The manufacturer prints the Type and Class on the label; non-ANSI garments carry no rating.

Technical. ANSI/ISEA 107-2020 (and 107-2015, which most labels still cite) sets minimum areas of background material and retroreflective material per class: Class 1 at least 217 sq in background and 155 sq in reflective; Class 2 at least 775 sq in background and 201 sq in reflective; Class 3 at least 1,240 sq in background and 310 sq in reflective, with sleeves; Class E supplemental garments at least 465 sq in background and 109 sq in reflective. Type R garments must meet Class 2 or 3; Type O is Class 1; Type P may be Class 2 or 3 with a lower background minimum. Flame-resistant hi-vis is tested separately (ASTM F1506, NFPA 2112, or ASTM D6413 for a self-extinguishing fabric) and is marked FR here only where the manufacturer rates it.
