Commuting, I wear mesh jacket, mesh over pants, Held Titan gloves, helmet, and A* Ridge (commuting) boots.
Spirited riding, I make sure to wear jeans under my over pants, my sidi vortice boots, everything else stays the same.
Track: leather suit, back protector, Helds, and Sidis (and of course helmet)
Depending on weather, I'll wear my leather jacket, otherwise, i just use the removable liners.
Always assume car drivers are blind, drunk or blind drunk and are liable to pull the biggest numbskull ****ups imaginable right in your path.
