Cotton hi-vis vest - where to buy?

[no_spam]

I need to find a long orange hi-vis vest ... it's easy to find them in polyester but, despite spending a long time on Google, I can't find cotton ones - are they available?

- that's yellow, but the manufacturer labelled as Helman and they might do an orange (GO/RT for rail use?) version?

or cut the sleeves off a cotton hi vis jacket?
