I've taken a Wanderlite all over the world for just what you describe. It's great for short trails/day hikes, museum hopping, etc. It's a fairly thick, durable fabric (420D nylon), not an ultrathin nylon that feels like it might tear. It rolls up to the size of a can of soda, so pretty compact yet it still unrolls to a standard full size (1925ci) pack. Plus it's made in USA. And it's well within your price range.
