Hi Vis — common questions
Straight answers about what we stock, how it is sold and which standard applies.
What class of hi vis do I need?
EN ISO 20471 sets three classes by how much high visibility material the garment carries. Class 1 needs 0.14 m² of fluorescent fabric and 0.10 m² of retroreflective tape. Class 2 needs 0.50 m² and 0.13 m². Class 3 needs 0.80 m² and 0.20 m². Higher class means more material, which is why a Class 3 garment is a jacket or a coverall rather than a vest. Only fluorescent yellow, orange and red certify, and reflective bands must be at least 50 mm wide.
Is a hi vis vest enough for working on a road?
A vest on its own reaches Class 2 at best. Class 3 is the one specified for working near faster traffic, and it has to be reached by the whole outfit: a Class 3 jacket covering the torso with reflective bands on the sleeves, or a Class 2 top worn with hi vis trousers that carry bands. Check the specification on the site, and check what the site you are working on demands.
Which colours are allowed?
Only three colours certify under EN ISO 20471: fluorescent yellow, orange and red. Anything else, including the popular navy or black lower halves, is a two-tone garment where only the certified fluorescent sections count towards the class.
Can hi vis be printed or embroidered?
Yes. Clothing House prints and embroiders in its own UK studio. Decoration must not cover the certified reflective and fluorescent areas, which limits placement on smaller garments such as vests. Decorated orders take 10 to 14 working days from artwork approval. Plain stock goes out in 3 to 5 working days.
