A self-massage roller having a bottle, a covering, and, optionally, a removable cap. The bottle provides a vessel for holding liquids. The covering includes a base layer and a plurality of nubs. The base layer overlays the outer surface of the bottle. Each nub in the plurality of nubs protrudes from the base layer in a direction radially away from the outer surface of the bottle. Each nub is a massage element, and the plurality of nubs forms a textured surface for myofascial release of certain muscles of the user. In another version, each nub is attached directly to the outer surface of the bottle without an intervening base layer. In versions with a cap, the cap may include a flip-up spout, or it may have a plunger valve that opens upon pulling the plunger outward and closes upon pushing in the plunger.
