Can't remember which one - one of the many on the RHS as you enter from the car park end.. Sue Ryder, Sobell House or BHF. Up on the RHS rack at the back of the shop with the other mens assortments.
I tried it on for a laugh and predictably it made my tubby 38-39" chest looks like a packet of shrink-wrapped sausages, so I suspect only proper racing snakes need apply.
Probably not a bad score if it's still there and you want some ostensibly decent gear for not a lot of money
