Rapha, nice but a bit pricey?

I posted this over in the police spotting thread, but fwiw since it seems relevant here recent research from the University of Bath found no benefit from high-vis.

I personally think there are. When my font light hits the hi-viz or the reflector bits on it that person is VERY visible. It might not be the colour but having those reflective strips on you really does make a difference.

Wonder if 3M can make a scotch tape reflective gilet that fits well.....
