We offer this lightweight set of two ropes made of one quarter inch braided nylon rope. They are strong yet compact for hanging a hammock while camping or when you wish to pack light for travel. A total of forty feet of rope, each twenty foot length is tied into a loop with a fisherman's knot. This allows you to throw the loop of rope over a branch, rafter, around the trunk of a tree or post, even a screw eye and pass the rope through itself for easy set up and take down--no knots to untie!
