I have an icon jacket and am buying some alpinestars track pants. My jacket came with a built in zipper and the other half which is already sewn into my street pants. I am guessing the alpinestars pants zipper wont be compatible with my jacket. Does anyone know where I should go that would have the half of the zipper that will be compatible with my icon jacket so I can have it sewn into my alpinestars pants? I have no idea where to go that stocks zippers/will sew them into leather pants. Any insight is appreciated.
