clear plastic one-layer boxes as well. One for musky plugs, another for bass, another for terminal tackle, etc. Easy to store, organize, and i take what i need for each outting instead of dragging ALL of my tackle with me.
Have a backpack with pliers etc. Its not waterproof though. I'm not sure which is better -- waterproof, or highly breathable. For me its the latter but to each his (or her) own.
