I always wear the following gear regardless of temp (today was about 90 and I wore it all):
New Helmet - I love it!
Old Helmet - Like it less than the SHOEI, but still very good.
Choice of jackets:
Vanson COBRA - FANTASTIC!
FirstGear Trekker (For trips, rainy days)
Olympia Kevlar Gloves - GREAT!
Vanson Pants - AWESOME!
Finally - SIDI OnROad Sympatex - 100% waterproof..
