That rang a bell. So I went out to No.2 shed. Just as I thought. An unused Aldi bib n brace, bought mail-order on a rec from here a couple of years ago. It's not a bad fit (I've another bib n brace where the zip finishes so high you'd have to have porn-star equipment to get up, over and out to take a leak) but the material is the kind of shiny nylon where anything you put on your leg - your hand, your arm, your rod- just slides off straight away. It feels like if you sat down you'd slip off your box. Who says nobody reviews stuff on here lol.
