We sell only USA made Nylon.
Nylon is the most common material used in sports nets. There is much "import" nylon on the market. This "import" nylon is often of a much lower quality than USA made nylon. Often this "import" nylon has only half the strength of USA made nylon. "Import" nylon often does not have the UV resisance of USA made nylon. (Some companies substitute polyester for nylon when nylon is hard to get. Good, but not as good as nylon.)
PE (polyethylene) is sold by many companies because it is cheap. (Polypropylene is about the same as PE.)
Ultra is the latest in high performance fibers. It is starting to gain in popularity, but it is still relatively expensive. Kevlar was the first high performance fiber used, but Kevlar does not have the strength and UV resistance as the more modern UHMWPE (ultra-high-molecular-weight-polyethyene) fibers that we call "Ultra". Ultra is manufactured by many companies with the most common trade names of Spectra and Dyneema.
