Hi Vis Hoodies are a very popular item of work clothing, the range expands every year to meet that demand.
In some environments hoodies can be considered a risk, the hood is a loose item of clothing that could become entangled / caught. A hoodie with a zip off hood like the XAX Fleece-Viz and Retro Fleece-Viz would be a wise option where the hood can be removed when working in an environments where a risk exists.
Waterproof Hoodies are one of the other recent developments. A Teflon coat on the Prime Mover HV317 means that when it rains, your hood can go up and you have similar protection to wearing a jacket, but without the bulk.
