DRY YOUR GEAR
Any bit of random string will probably do, however, the Sea To Summit Lite Line Clothesline is a better solution with additional features. The Clothesline has “two parallel cords with rubber 'beads' that can slide along the cords. Hang the clothesline by wrapping each end around a convenient suspension point, then hooking it in place.” It's 3.5m (12.5 ft) long and comes with a small nylon carry pouch.
