A bit over five years ago I recall seeing a pretty slow runner wearing one of those every weekend
for almost a year to the various coffee/bagel shops his running club frequented after their
weekly long runs. This guy had a personal best run about an hour over the cutoff for Boston
qualification for his age group.
He signed up for some charity and got to run Boston and hence got the jacket.
Most of that crowd appeared to be too heavy to be decent runners. A lot of them will probably be
wearing those jackets on weekends and "impressing" their friends too.
