Backpack with an elastic breathable fabric

Abstract

A backpack with an elastic breathable fabric contains a body and an elastic breathable fabric. The body includes an outer surface, a back surface, at least one strap connected with the back surface, a receiving space defined between the outer surface and the back surface, and a contacting portion formed on a central position of the back surface. The elastic breathable fabric, is formed in a mesh shape, has a pre-set tension, and is fixed on the contacting portion of the back surface of the body. Also, the elastic breathable fabric includes a plurality of tiny holes so that the elastic breathable fabric communicates with the receiving space. Thereby, when the elastic breathable fabric contacts with the user's back, it provides breathable wicking function. Also, the elastic breathable fabric has the pre-set tension to recover elasticity quickly, thus reducing carrying pressure to user's body.
