I have a storm 2620, which fits a rig and two jumpsuits easily, plus other small stuff. I also have a 2750 which can easily fit a rig, my helmet bag, two jumpsuits, and some other junk. You can also get two rigs (snugly) into ththe 2750. I got the "storm" versions instead of the "pelican" versions because they are a couple of lbs lighter, and with my gear I'm always bumping right up against the 50lb checked bag limits when I fly. Mine have at least half a million miles of commercial flights on them and they're pretty much indestructible...
