I am looking for a jacket that can be used in the spring, hot summer and the fall. My main concerns are for the jacket to have good protection in case I fall off my scooter, keep me cool in the hot summer and be water proof by being built in or something that can be added via a zipper. I prefer Gortex as it breaths as I do not want to sweat to death when it is hot and starts raining. I priced out the Savanaha 2 BMW jacket and I was surprised by the cost. $475 for the jacket and $200 for the Gortex liner. Does anyone have any suggestions for a jacket that will meet my criteria that is less expensive than $700. If not, I may have to bite the bullet and open the wallet. Thanks in advance.
