Cheap Hi-Vis Vest from Harbor Freight $6.99.

Western Safety 3604 Reflective Mesh Vest


- mesh breathes
- hi-vis-shiny-as-all-heck-stripes
- after a full year of commuting the orange has faded but the stripes are perfect

Great front and back coverage, Back is shorter than front, light weight, mesh allows air to move freely thru, no flapping (for most part). I cut a slit in the back horizontal stripe and can hang a blinky from the back if I want.

I use a backpack occasionally. I have one of the 'slow moving object' triangles for the backpack. Wrap the strap around the base of the backpack and gets me noticed.
