When I was a kid, I prowled the boonies wearing a WWII era GI pistol belt, canteen, and first aid pouch. Many years later, before I went to a hydration pack, I did basically the same, with some newer equipment. Canteen pouch with ALICE clips (less flopping around than the old wires), and a new version first aid kit. I pretty much gutted the kit and inserted my own stuff, turning it into a combo FAK and PSK. With the ALICE clips you can wear one on pretty much any belt, if you like belt stuff...
