One of the things I noticed is that in DayZ, you either stuff your things in your pockets or on your vest pouches (second line) or in your backpack (third line). The first line, which is your belt/waistband is never really used. What I suggest is that we can utilize our belts (perhaps we can find different kind of belts) and attach first aid kits, multi-tools and duty/concealed carry holsters on the belt. That'd make the customization more interesting and have more slots for your weapon or whatever while being realistic.
