This one in size 12. http://www.bikestop.co.uk/detail.php?id=1047
Not sure how they really work their sizing but this is a large back protector for anybody 6 foot or over. The waist band is velcro and adjustable from skinny to big, I’m about a medium probably, size 36 waist.
Never been worn on the bike, just indoors to try it on, brand new in black with red Dainese logo. Ali honeycombe centre which will compress on impact to absorb the shock before it gets to your spine. Hard plastic outer sections which move against each other to give flexibility like an armadilo shell.
Only selling because I already have a Forcefield protector and find that slightly more comfortable. £75 delivered to BM or Ace.
