I bought one of these from a franchised shop in Sheringham, Norfolk. I must confess I have not actually worn it in public yet. I think you have to be in the right crowd with a similar mind set to get away with it ! The best buys in my opinion are the mugs. Great big workshop size mugs with a large handle, wonderful when full of strong tea.
There are are similar designs for all sorts of sports/ interests eg golf, camper vans, motor cycling etc. Just the thing to ask for when stumped when asked " what do you want for a present ?" If no shop locally get them off the website.
