At our place there has been a massive thing with gloves over last few months.
We have been sent a sizing chart to print out at A4 to use for ordering. Feedback is the sizing is pretty good.
They are colour coded so the cut level rating is easily identifiable.
I've a feeling they are more expensive than generic/ebay but they probably get a decent corporate rate..
Their website has loads of gloves to choose from.. Traffi is the firm,if i'm allowed to say..
On some main contractor sites i have seen H+S guys inspecting gloves on operatives and not allowing them due to CP value being too low or not marked clearly on gloves. I've a feeling we will see more of this approach.
