A knockdown golf bag for being component size self-compensating. The knockdown golf bag includes a bag, an upper frame, a lower frame, rods, and a partition. The bag is collapsible, and as such, has a collapsed mode and an uncollapsed mode. The upper frame is replaceably attached to the bag. The lower frame is replaceably attached to the bag. The rods extend from, and between, the upper frame and the lower frame to maintain the bag in the uncollapsed mode thereof, and when removed, allow the bag to achieve the collapsed mode thereof. The partition extends within the bag, from the upper frame to the lower frame, and is elastometrically attached to the lower frame so as to allow the golf bag to be component size self-compensating.
