## Abstract

Provided is a method of manufacturing outdoor clothing requiring no seam tape and having an enhanced waterproof function in which a waterproof function is further improved. The method includes: preparing an outer fabric in which surface contact portions of a first outer fabric and a second outer fabric are bonded to a bottom surface of the first outer fabric; preparing a structure in which a first adhesive layer, a membrane, and a second adhesive layer are sequentially disposed on an upper surface of the inner fabric; and bonding the structure and the outer fabric.
