On day 1, I usually go for a hoodie, cargo pants, and a backpack. I also usually load down with a pouch. However, if I find a leather jacket, army jacket, or the like, I switch the hoodie for it, if I find army pants, I switch those with the cargos, and if I get a leather backpack, I swap the backpack for it. If I get ahold of a military rucksack somehow, I get on a less encumbering shirt and wear the sack.
Of course, after running across some dead military squads, I generally end up with +200 storage, although by that point I have a lot of heavy stuff and the storage is nearly moot. Still handy to have some form of external vehicle storage, like a shopping cart.
