The unlined Showers Pass jackets roll up to jersey pocket small easily (I've done it many times while riding) and are very well thought out jackets.

I use the lined jackets from SP for commuting as the vapor barrier lasts far longer without brushing wet hands that grab on it. But for long rides, the SP jackets are great until that accident happens. And when it does, that jacket gets demoted to a dry weather spring/fall and cold jacket, working very well there.
