I have 2 vests like this in XL: (lights up REALLY well at night)
and a reflective harness-like vest-y thing-a-ma-jig also in XL:
(can't find a pic of it but it is orange with white reflective strips)
Finally found what I need in size Woolly Mammoth so I don't have to "make do any more".
Free to anyone local (Dallas/Richardson Area) who can pick them up.
