Mark's suggestions are right on if you want a softshell close to the original concept, such as Rab's Vapor Rise line. However, it is hard to answer your question given how broad the category of "softshell" has become. The term now covers fully waterproof pieces as well as just plain windshells- so outlining specific qualities that you want in a shell is a good starting point.
Regardless, if you think Epic is a softshell, Wild Things has a half-zip shell in their Performance line. OR has a pullover Contour Windshirt made from, what I consider, a softshell fabric.
