As if paracord wasn't amazing enough, here's the Dyna X Paracord. Lighter, stronger, and more durable than the common paracord, it is also designed to avoid stretching (a feature required of 550 paracord) and it absorbs no water.

With more than two times the minimum tensile strength as 550 paracord, Atwood Rope Dyna X is the next level of survival cords. Its composition allows it to float on water, it's super-slick, and it has nearly zero stretch. If your application requires more than ordinary paracord can deliver, this is certainly worth considering.
