SunnySports S This pack does not come with a rain cover. It does have water resistant zippers though, but I guess that's really no help if you get caught in a downpour. As far as torso length, North Face doesn't give specific lengths on this pack, but the usual sizes are Small (15"-18"in/38-46cm) Medium (17"-20"in/43-51cm) Large(19"-20"in /48-56cm). This pack is a medium. Stay safe and have fun out there! Neal
