I personally keep my kits in size by restraining them with containers and packs. Like the pouch I show it will always stay that size, now the WEIGHT may change but that's another concern to think about afterwards. Rarely do i attach anything to my packs or pouches as its just way to bulky for me. I dont wanna look like a pack mule on a trail nor do I want a buncha stuff wagging, wacking and swinging all over with every step I take. Thats why the Alum water bottles with the "handy" clips on their caps confuses me. Who in the world wants a big bottle of water flapping around on them throwing off your balance and smacking you around as you walk?
