I've been through a bunch of gear in the last 200,000 miles. The pieces that have stuck around:
- Aerostich Roadcrafter 1-piece (in Hi-Viz!)
- Alpinestars MX-1 1-piece leathers

The former is worn for commuting, long rides, errands, riding, and other riding.
The latter is worn for sport riding and track days.
My current helmet is a Shoei X-12 and my next helmet will be an RF1200 or Qwest.
Boots are Sidi Vortices and gloves are Lee Parks Deerskin or Alpinestars GP Pro.

In 200,000 miles, I've fallen once. It was last year. No one is immune. (And don't corner hard in the snow.)
