How do I choose the right size? Are WERKVIS sizes international?

All WERKVIS garments follow international sizing standards, though cut and fit may vary slightly between styles.


We recommend referring to the detailed size chart on each product page and comparing it with your body measurements (chest, waist, hips, height, etc.).


If you are between sizes, choose the smaller size for a closer fit or the larger size for a more relaxed fit.


If the size is still not perfect, there’s no need to worry! We offer convenient exchanges to help you find the right fit.

What materials are used in WERKVIS products?

WERKVIS products are made from durable, high-visibility fabrics designed to balance comfort with safety and performance in different work environments.
Most garments use polyester or poly-cotton blends, which are abrasion-resistant, colorfast, and retain their brightness and functionality even after multiple washes.

How should I wash and care for WERKVIS safety clothing?
  • To maintain the high visibility, color, and durability of your garments, machine wash at 40°C or below using mild detergent.
  • Avoid bleach and fabric softeners, which can damage reflective materials.
  • Do not tumble dry at high temperatures or iron directly on reflective areas.
  • Proper care ensures your clothing continues to meet EN ISO 20471 safety standards.
