I have one the removable ID holder makes it easy to get through the gate, the front pocket can fit smokes and a cell phone, the rear pocket is great for holding gloves when chillin or a soda while riding. Kind of expesive at 50 bucks but while worth it it fits over my leathers well. Definatly has paid for it self in not having to get my ID out at the gate. Fits in bike trunk well too.
Just thought Id pass the word.
FYI for you civilians, most military members are required to wear reflective vests, usually of the construction worker type.
