I got my first Illiminite vest at the Richmond Marathon Expo around 2012. Its reflective beads lost their mojo and I replaced it with the Venture packable. It is very thin (packable). It looks bright enough when I run at night. My only gripe is that its zippers are very small. They are tough to find when moving and routinely snag on the vest material.
Kept getting wrong size. Done with them.
