EN ISO 20471 sets minimum areas of fluorescent background and retroreflective material for each class, so a company logo on a site waistcoat has to be modest, sit on background material and stay off the tape.
Hi-vis fabric is thin polyester or open mesh that ripples under ordinary density. We build the lightest file that still covers, with stabilising underlay, so the garment stays flat.
Kitting out the rest of the team? See workwear digitising for polos, softshells and beanies, and chest logo sizing for small logos.
We supply the embroidery file; whether a decorated garment still meets its class is for the garment manufacturer and employer to confirm. Keep logos small on garments near the minimum.
