The invention relates to a climate tube (10), particularly for airplanes, having an inner layer (12) and an outer layer (16) made of a fiber composite plastic material. In order to achieve high stiffness, while simultaneously maintaining a low weight, and in order to achieve good thermal insulation properties, an at least nearly completely circumferential honeycomb core (14), which is rigidly connected to the inner layer (12) and the outer layer (16), is disposed between the inner layer (12) and the outer layer (16), the radial extension of said core being large compared to the radial extensions of the inner layer (12) and the outer layer (16).
