sheesh... you try to offer info to people who might be interested and what do you get?
It's not the official PBP gilet at all. It's a night-time use regulation conforming gilet as recommended by the FFCT. You are quite free to wear something else for PBP if you wish (subject to scrutineers approval of course).
Personally, I think it's a decent product and have ordered one, not just for PBP but for night-time wear generally. It's a functional gilet, good thought into design and legal high-viz.
