Hi people. I am lucky to live in a part of the world that is quite bike friendly most of the year, but summer is pretty gruesome.. very humid. I am wanting to get a leather jacket for chrissy, so am looking at the 'coolest' one. There are perforated ones.. the Joe rocket has an apparent cooling system with vents. Can anyone offer advice as to what they have found the best ? It never gets cold here, so I dont need any protection when our 'winter' comes around.
