Liddle are selling work trousers. They are snug fitting as non work trousers. Ie if clambering up a ladder and weaving through lofts and ets, you will be exposing as much bum as ever as they stick to your sweaty legs and get pulled by your knees.
They seem OK though if you can be bothered with fly buttons. Get the size up from the one you think is indicated. Where can I get a pair of cheap hardwaring, well pocketed work trousers?
I get the impression someone found the key to a warehouse full of stuff left over from the bad old days in the east.
