PROBLEM TO BE SOLVED: To provide a long-lasting and durable super abrasion-resistant hose capable of preventing deterioration of an ultra high molecular weight polyethylene layer due to ultraviolet rays that causes the cracking of the hose. SOLUTION: The super abrasion-resistant hose has an inner rubber, a pressure-resistant reinforcing layer placed on the inner rubber, an outer rubber placed on the pressure-resistant reinforcing layer and composed of at least one layer, and an ultra high molecular weight polyethylene layer placed on the outer rubber, and an anti-oxidant is added to the rubber composition constituting at least the outermost layer of the outer rubber.
