I'm looking to create a backpack specifically for going to fan conventions. Specific features I'm looking for include exterior USB ports for phone charging, clear plastic faces on the front of the bag to display pins and patches, and modular Velcroed/buckled pouches that can attach to the front of the bag. These are in addition to custom sized pouches and pockets in the bag itself.
