i use an old jansport bookbag. i have 3 plano 3700 boxes. one with terminal tackle and 2 for hardbaits and jigs. i also use a plano soft plastics bag for my plastics. i carry two boxes ( have to mix ad match jigs and hard baits ) with and the plastics bag in the front pocket and pliers, scissors, leader line and other tools in the front two pockets. just find an old bookbag and take your time planning how to fit the most tackle in there while still retaining comfort.
