The stuff that you MUST use is pretty simple and straight forward.
Helmet (I wear 1/2 - nonDOT most of the time, and full face when it gets super cold - like 20deg)
Gloves - I wear fingerless gel gloves for grip
Heavy leather vest - You would be surprised at the number of rocks and debris this thing takes. Also helps keep the core warm.
Heavy Leather boots - ALWAYS wear over the ankle boots with good tread. ALWAYS. I prefer Red Wing motorcycle boots. I wear them every single day and even walk miles at work in them. They're awesome!

Outside of that it is all about what you can be comfortable in. I usually start wearing my Cortech denim jacket when it gets cool. Same with my leather chaps. Otherwise I don't usually wear one. Like they say, the colder it is, the safer I ride. lol.

If you do wear chaps/pants and jacket all the time. Make sure that you get ones with removeable liners and zipper openings for air. That way you're covered when it's hot out, but can still bundle up when it's cold.
