The invention relates to an enteral feeding tube comprising a jejunal tube which is arranged in jejunum and comprises a proximal end, a distal end and a lumen between said two ends. The jejunal tube comprises at least two layers, including an outer first layer and a second layer adjacent to the outer first layer, the outer first layer comprising a material which is harder than the material of the second layer. The jejunal tube may have a triple-layer structure that includes an outer layer, an inner layer, and an internal layer, the internal layer may be softer than the outer and inner layers. The multiple-layer structure of the jejunal tube having materials of different hardnesses improves the flexibility, advancing behavior and buckling resistance of the feeding tube. The invention also relates to a tube system including the enteral feeding tube and a gastric tube.
