The Rallt Camping Hammock safely holds up to 500 pounds. It does so by using a strong diamond ripstop fabric that's abrasion-resistant and very tear-resistant. The structural seams are triple-stitched. All the rope is 6mm thick and nautical-grade - yes, the same rope used on sailboats. We use a breathable nylon body so that there is some give. That makes the body more durable and more comfortable. Any stretch in the rope means the hammock will slowly sag lower and lower as the night goes on. You might end up on the ground in the middle of the night. Our ropes are all non-stretch polypropylene. Your hammock also needs to be big enough for you and maybe one more. At 10 feet long and just over 6 feet wide, it's comfortable for two and an absolute dream for one. We include two sections of rope for hanging. Each is a generous 10 feet long, making it possible to hang your hammock even when the trees are far apart - even over 20 feet.
