I've been wearing durakit trousers the last few months, and now it's turning colder I've got thir body warmer too. On their website they do a range of reflective workwear, inc dungerees.
they wash up like new, have loads of pockets, definately hardwearing and as they're semi waterproof they dry out really quickly if you do get wet.
I got some iron inkjet transfer online which I've printed my logo.
I think B&Q sell them, but I picked them up locally cheaper than the RRP
