I'm looking for a new way to store and carry my large first aid kit. I managed to cut myself in my thumb and messing with my first aid kit, I wasn't totally happy with what I had.

Currently I have a clipbox with a tray inside. I put the small and regularly used stuff on top in the tray, under need are the larger things. I had to dig for the gauze, because it was under the things needed for larger injury's. I choose the clipbox because it's light weight, rainproof, inexpensive, can be organised and the clips are far easier to open than zippers. Currently thinking of just getting a larger clipbox and add dividers/trays.

But I would like more input on what to get. Anybody know a different system which can be easily be moved, organized, easily accessible with one hand and is rainproof?
