5 pairs underwear. 2 t-shirts. 2 pairs BDU pants. 7 pairs socks. 1 pair exercise shorts. 1 pair swimsuit. 1 Nomex hood. 1 pair rain pants. 1 sweat shirt. That's what I've worn for up to a month, no laundry. Only get to take one pack with you, so clothing is kept to a minimum... I learned swimsuits are great in the field cause you can wear 'em for weeks so long as you can jump in the shower every now and then. Athletic shorts also take a while to get funky when used as underwear. .
