There's only so much survival gear that you can easily carry. That's what makes Doug and Chelsey Luehr's invention so awesome. The whole thing unravels into 80 feet of 550 strength paracord that you can use to MacGyver your way out of whatever mess you've gotten yourself into.

One downside to this design is that it's probably not a sound platform for carrying gear. I need a thick leather belt to hold up my everyday carry, and I would think that most people who are into survival prep would, too.
