I have a pair of these in black, https://www.dainese.com/gb/en/motorbike/safety/double-chest-201876081.html, purchased from Ducati. Bought because I was struck in the chest by a bird whilst on track and not wearing a chest protector, ending up with quite extensive bruising. Worn a couple of times but never had the opportunity again to test the effectiveness. I have a Helite air vest now so surplus to requirements. You need a Dainese jacket with the big internal pockets to accommodate them. £30 posted. Andy
Just been hunting for a surface mounted double socket box that my memory tells me I have somewhere and all I have found so far, is this 2 piece chest protector. Anyone ? Andy
