Full face modular helmet with reflector tape at all times -- it's the law in NJ (for helmets -- not full face ones). Armored riding jacket with a reflector stripe ...
http://www.corazzo.net/mens-5.0-jacket... at all times if I'm going on a highway, or into Philly. Around my town I'll go jacket-less if it's 65 or higher. In the winter I have a heavy leather coat, and I plan to purchase a good balaclava this winter.
I generally wear pants if going on a heavy or long trip, but will do shorts for around town, or if it's really hot.
Sneakers or heavy shoes/boots, but never sandals -- like my toes too much. Gloves if not too hot, but lately I've gone without as it's easier to get to my
money at the bridge tolls.
If it's raining, snowing, or below freezing I won't take the scooter out. Too dangerous.
