#3 (or 4?) for the Joe Rocket Alter Ego. For cold/wet weather there is a zip in waterproof inner liner. As it warms up, take that out. Then when it get really warm, the outer panels and sleeves zip off to give a mess jacket with armour still in the elbows and back. Very versitile.

 

Kevlar airmesh jacket for me made by cycleport.

 

Touring jacket? Is this like a smoking jacket or something? If you need a jacket during summer you're living in the wrong climate.
