I have been actaully trying to come up with a modular system but I gave up due to the fact that I couldn't get any containers to fit the modules in. <br>So I ended up with many diff kits - every day kit, urban kit, wilderness kit etc. Its semi modular in the sense that if I'm going somewhere where more gear is needed, I just grab an additional kit. It leaves me with more containers sure, but I like the redundancy. I am comforted by the fact that I have lots more essential equipment like matches (and 2 or more sparklites!!)(which doesn't take up too much space).<br>Plus it saves me from trying to find a suitable container to fit each module into and to repack each module each time it is needed - just EDC, EDC + USK, EDC + USK + PSK<br><br>
