Stupid me! I have some jog-lite reflective bands that attach with velcro on my backpack. I just loop them around a couple of straps on the pack.
Heres a pic. the two bright yellow ones in the center of dull yellow ones are jog lites band. They are not as bright as the saftey vest above but they do work.
