I wear an Optic Yellow jersey when riding in warm weather. I got used to wearing the fluorescent vests and jackets at work as an engineer on construction sites for the U.S. Navy. supposedly the Optic Yellow is not a naturally occurring in nature and stands out to the human eye. (according to scientist and engineers in the fire truck industry.) Most of the mfgr have a line of the fluorescent clothing including the reflective stripes. Pearl Izumi is the brand I like, gave my wife one of their wind/rain jackets last Christmas and she wears it all of the time. I'm going to add one to my kit soon, but a heavier model with a Gore-Tex lining for breathability.
