This strap system is hands down the strongest and most durable on the market today. Built using climbing grade webbing and construction techniques, we've built a system nearly 10x stronger than the competition. Our C1 Kits come with one 180cm CE Certified climbing runner rated to 22kn (over 4000lbs) and one 240cm Hammock Chain. Our unique Hammock Chain is built using a series of five individually sewn loops attached to a 180cm runner. This allows for 2 feet of easy adjustment and is significantly stronger than daisy chains, knotted cord, or cam buckle adjustment systems. Our C2 Kit comes with two 240cm Hammock Chains allowing for twice the adjustment range.
