I wear a 2-piece AGV red/white/black leather suit.

The jacket unzips away from the pants. Very warm during cold weather, very hot during summer.

Under the jacket I have a highvelocitygear.com back protector.

Suit was used, cost about $300. Back protector came with an armor suit. About $180 total.

 

ICON motorhead jacket.

has the removable liner, elbow, shoulder, and spine pads. plus it looks totally bad ***.

 

For commuting to work or running errands, and staying warm a simple Tourmaster layered mesh jacket.
It has some removable CE padding in the shoulders, back, and elbow areas.

For serious twisty or track day riding a Joe Rocket all leather, fully padded Supermoto Jacket.
