I'm looking to start commuting with a safety vest, but I'm not sure where to start. I own two, one nice plastic heavy duty mesh one left over from my days in EMS with "Emergency Management" and "Search and Rescue" bolded on the reflective tape, and a simple one from Harbor Freight. I commute with a Camelbak Mule, and I'm looking for ways to incorporate both. I don't want to give up the Camelbak, since it not only allows me quick hydration, but I'm able to carry everything I need for a long day in various locations in my work truck. I take the bag off, put it in my truck, and I'm good to go. I've tried draping the vest over the back of the bag, but it made things a little too tight.

Anyway, give me some suggestions. I'm running out of ideas over here.
