[0011] Preferably, the air hole is the oval hole, and the air holes are arrayed on the fabric tape main part.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By using hot-press bonding to fix the protective edge to the edge of the webbing body, the protective edge protects the edge of the webbing body and improves the wear resistance of the webbing edge. The EPDM rubber film hot-press bonded to the outer surface of the rubber sleeve increases the hardness and wear resistance of the outer surface of the protective edge, reducing wear on the protective edge. The integrally formed connecting strip on the inner surface of the rubber sleeve is fixed in the positioning hole opened on the edge of the webbing body, which increases the stability of the connection between the webbing body and the protective edge and prevents the protective edge from being squeezed and separated from the webbing body. The webbing body is provided with ventilation holes for ventilation, which increases the breathability of the webbing body.

[0014] 2. The webbing body is composed of a memory foam pad, a polyester fiber layer, and a moisture-wicking fiber layer. The two polyester fiber layers and the two moisture-wicking fiber layers are symmetrical about the memory foam pad. The two polyester fiber layers are bonded to the two sides of the memory foam pad, while the two moisture-wicking fiber layers are bonded to the outer surface of the two polyester fiber layers. This allows the memory foam pad to increase the cushioning of the webbing body when it is compressed. The polyester fiber layer and the moisture-wicking fiber layer work together to ensure the structural strength of the webbing body, while the moisture-wicking fiber layer also increases the heat dissipation performance of the webbing body.
