As any grunt knows, when you're in the field for awhile you want some clean, dry socks and drawers. Zip-Lock baggies are a real life saver. One sandwich sized baggie holds one pair of underwear and one pair of socks. When packing, simply zip the items into the bag leaving a small opening on one end. Then either squeeze the excess air out or suck it out before sealing it all the way. This saves space in the ruck for other necessary items and ensures that after walking through chest deep swamps that you still have clean underwear for when you face the enemy (just like mom always wanted).
