I'm always looking for ways to shave hammock weight.
Today, I learned that 1.5 inch polypro is lighter than 1" polyester - about 1/2. I've been using the polypro but got some polyester as a test. Nylon weighs about 50 percent more than the polypro. So far, I have a couple of hundred nights hanging from polypro. The only problem was when a tried 1" instead of 1.5. It didn't fail, but it was getting ready to. My two 12 foot lines in 1.5 polypro weigh 5 ounces together. No hardware, no tree huggers, just the simple lines.
