Have you seen high-visibility 'safety' (half/short) vests (some call them jackets or sweaters)?

They come in many colors bright orange, bright green, bright blue (and yes bright yellow ;-) They are very compact, light, and folded away into small bag. They are from $4-8 a piece in AUS (made in CN).

In AUS wearers get attention they need -- as workers tending to a safety/emergency situation. People usually give way to them. The question for you is : Life or Fashion?
