Material handling hose having an abrasion-resistant cover element is disclosed. The hose comprises an inner tube, a reinforcement member, an intermediate layer and the abrasion-resistant cover element. The cover element does not cover the entire surface of the intermediate layer, but includes apertures or gaps through which a portion of the underlying intermediate layer is exposed to the outside environment. The apertures allow for venting of high volatility materials through the hose body, and provide regions of relatively high coefficient of friction, to facilitate handling of the hose.
