The present invention relates to a backpack that can be used by combining a plurality of storage spaces (expansion packs) at the lower portion of a basic backpack as necessary. The present invention comprises a bag main body which is selectively opened and closed to form an accommodation space in which goods are accommodated; shoulder straps which are provided as a pair on both sides of the rear surface of the bag main body and seated on the shoulders of a user so that the bag main body is placed on the back of the user; and at least one expansion pack which has an upper portion opened to form a storage space therein, is selectively fastened with the lower portion of the bag main body, and expands the accommodation space of the bag main body. The bottom portion forming the bottom surface of the bag main body is fastened to the front portion and both side surfaces of the bag main body via a bottom zipper portion and is opened/closed by a bottom zipper. The expansion pack comprises: an upper zipper which is provided along the upper front portion and both side surfaces of the expansion pack and is coupled to part of the bottom zipper which is fixed to the bag main body side while the bottom surface portion is opened; a bottom plate forming the bottom surface of the expansion pack; and a lower zipper which is formed along the front portion and both side surfaces of the bottom plate to fasten the bottom plate to the lower portion of the expansion pack through zip coupling. According to the present invention, expansion packs can be continuously coupled to the lower portion of the backpack as necessary in order to secure a required amount of storage space, and thus, there is an effect of securing expandability of the storage space without limitation.
