Finally the correct answer. Thanks "Blacked"!!! While I was in Recon we used 550 all the time. We would create wraps to go on our Boonie covers, on our packs, dummy cords for gear (so if you dropped gear from your pack such as a compass, knife, etc, it wouldnt be gone forever, just until you realized it got loose). It was easy to get in the military because it is widely used for parachutes. Hence the term parachute cord. When you see a parachute on tv, it's the lines going from the jumper to the chute (the ones you always see people get wrapped up in).
