Alternatively, if you don't mind the dorky crossing-guard look, the Xinglet.
Shoulder and waist straps are slightly stretchy and fully adjustable, so you can wear it over summer or winter clothes, it doesn't flap in the wind, and it doesn't greatly interfere with your jersey and/or jacket breathing. Plus, since it's an over-garment, it only needs occasional washing.
ETA: I hung my Voler hi-viz jerseys out on the line the other day in bright sunshine, and I literally could not look at them, they were so bright
