Paracord provides one of the most versatile ropes ever designed. Don't confuse this mil spec 550 lb. test Parachute Cord with the numerous imitations on the market. This is the official product used by the U.S. Military. This sturdy flexible “rope” primarily serves in the construction of parachutes. Mil-spec paracord consists of an outer sheath covering 7 smaller nylon cords which, when split apart, work for sewing or any other purpose that requires strong thread. The only thing limiting the uses of this cord is the user’s imagination, from shelter construction to first aid. This is a must have for any survival kit.
