ZIMAI Shanghai Zimai Safety Technology Co., Limitado. has been exporting PPE for over 30 años. Its vests illustrate what should be covered in a hi vis safety vest buying guide. Verify the class, cloth, tape, tamaño, and documents. If one of these is weak, the buyer might be in trouble.

A Hi Vis Safety Vest Buying Guide for Importers: Five Checks Before You Order
Five checks tell you if a vest is ready for export. Look at each one.
- Clase: the visibility level the vest lists.
- Tela: the bright base layer.
- Cinta: how wide it is and where it sits.
- Apresto: the full range, with ladies’ tamaños.
- Papers: certificates and export record.
A vest that passes all five is a safer buy.
What Do Visibility Classes Mean on a Vest Label?
Visibility grades indicate the amount of bright and reflective material on a garment. EN ISO 20471:2013 defines three classifications of High visibility clothing in high-risk circumstances must meet this international standard. The tape on these clothing should be not less than 50 mm broad.
The highest level is class 3. Clase 1 is the lowest one. In your personal risk evaluation you choose the appropriate class. For road work the ZIMAI standards website links to UK road-work advice.
Class Table for EN ISO 20471
| Clase | Nivel | mín.. material de antecedentes | mín.. material retrorreflectante |
| Clase 3 | Highest level | 0.80 m² | 0.20 m² |
| Clase 2 | Middle level | 0.50 m² | 0.13 m² |
| Clase 1 | Low level | 0.14 m² | 0.10 m² |
The ZIMAI pages for HV001, HV002, HV003, HV005, HV007 and HV015 list EN ISO 20471:2013 Clase II. That is the same as Class 2 in the table above.
Which Fluorescent Fabric Should You Ask For?
The brilliant base layer of a vest is made from fluorescent cloth. It helps people notice the person in daytime.
Standard ZIMAI vests are made from 120 gsm polyester knit fluo cloth. tiene 155 Tejido fluorescente de punto de poliéster retardante de llama gsm. Both are available in Hi-Vi Orange and Hi-Vi Yellow.
gsm indicates grams per square meter. Ask each provider to write down the fabric type, peso, and color name. The weight lets you compare two quotations.
¿Qué ancho debe tener la cinta reflectante?, and Where Does It Go?
Reflective tape should be at least 50 mm wide under EN ISO 20471. ZIMAI vests use 5 cinta de cm. That is the same as 50 milímetros.
Tape Position by Model
- HV001, HV005 and HV015: shoulder and waist
- HV002: waist only
- HV003: segmented tape on shoulder and waist
- HV007: flame retardant tape on shoulder and waist
- HV006: 5 cinta de cm, but its page lists no position
The placement of the tape affects the appearance of the worker from the side and from behind. Choose the spot that matches the job. Cut into small lengths (like on the HV003): Segmented tape It isn’t a lengthy strip.
How Do Day and Night Visibility Work Together?
High visibility apparel is effective for two reasons. Fluorescent fabric works in daylight. Reflective tape is great in the dark.
You may see the similar division in EN 17353:2020 on the ZIMAI standards site. There are three kinds of gear in that specification.
Types in EN 17353
- Type A: for daylight only. It uses fluorescent material alone.
- Type B: for the dark only. It uses retroreflective material alone.
- Type AB: for day, dusk and dark. It uses both materials.
ZIMAI vests contain luminous fabric and reflective tape. This is good for work that goes from daylight to evening.
How Do You Handle Vest Sizing for a Mixed Crew?
ZIMAI vests available in sizes S-5XL. The HV006 Reflective Harness is available in Men’s and Ladies’ sizes.
A mixed crew need the whole range in each order. Not everyone will be in middle sizes. No body measurements are given on the site. Before deciding how many of each size to purchase ask for a sizing chart.
Which Vests Have Extra Features?
Some tasks demand more than just a basic vest. The HV003 and HV005 are multi-pocket models. No information about pockets on their pages. The HV015 is a double color vest. The HV007 is constructed of flame retardant fabric and adhesive. The HV800 is designed for cold weather.
