This is my 3rd Joe Rocket jacket, and my 1st one that's leather. I absolutely love the Joe Rocket jackets - fit, protection, styling. This jacket is quite warm during the cooler days and breathes pretty well in warmer weather. The warmest it's been so far is the 80's and I wasn't too hot. There are removable panels on each side of the jacket allowing your underarms and sides of your torso to breathe. Overall, excellent leather jacket for the price.
