I have one of these to use as a con kit. It rocks. It is roomy enough to pack the stuff you need to carry around all day, but small and light enough to not get in the way while doing so. With my previous bag of holding, the bag would become a shapeless lump and I would spend a lot of time looking for stuff. With this bag, it is easy to find everything. It rocks. I just need more Velcro patches to put on the outside.
