You know what's cool? How about a plain black vest that matches everything, has a breathable mesh back, reflective accent, and three pockets?
These are made in the U.S.A. in conjunction with Twin Six and are just the thing for cooler weather rides. If you don't need it just shove it in your jersey pockets, or keep it forever and always in your back pack in case of emergencies.
