I have the large case, it's just about right for starting out and makes a great way to carry your gear. The case is 11" X 6.5" and comes with a system of velcro flex panels to keep your gear organized and in place. I really like the combination of large and small panels, and the Velcro backing allows me to change the layout really easy.
I've also got the Vault Super Pack, this allows further customization of the layout, and allows you to let your imagination run wild. The pack includes:
- 2 Large Parts Pouches.
- 2 Small Parts Pouches.
- 2 Stick Strips.
- 4 Clip Strips (2 long + 2 short).
I for one haven't used the Super Pack much, I think I'll get a much bigger case, or maybe a second one. I have items that aren't friendly with the loop panels, and would benefit from some additional organization.
I think the Vault system is really neat, it helps organize, and protect my EDC gear. I usually throw my gear in my luggage when I go on a trip, now I'll be able keep them separate and laid out more methodically. I'm impressed by the versatility of the case, and I think it's a great way to organize and even showcase my favorite gear.
