I have an xtremely Hi-vis yellow jacket from Sears. Craftsman brand. It's the kind of color you see on highway workers. Reflective stripes abound. I think it looks pretty good on me too.
Got "Sliders" winter gloves almost the same color. And a bright white full coverage helmet. You'd think nobody could possibly miss seeing me right? I average maybe one close call every two weeks from a driver who looked in my direction and didn't see me. Oh and my scoot is Kymco metalic ORANGE. I do tend to get a lot of long stares from other riders, though.
