Hi all. I will have a look and see how many are hanging around at work and post back here for whoever wants one. As I say it has our comapny logo on it on the front and that can easily be coloured in with a thick black marker pen.
As for them being not very visible I have to disagree. Often I have seen the police next to the track when something has happened or they are looking for someone(they wear both orange and the yellow/green ones) and the orange ones stand out miles better everytime. That of course is just my opinion and I am not saying at all that the green ones are no-good. Just basing it on my experience in all kinds of weather conditions, light etc.
