Nylon webbing is the strongest and long-lasting webbing. Flat nylon webbing has a tensile strength of 270 to 5,500 pounds per 1-inch width.
Nylon is also well known for its capability to stretch without breaking and return to its original shape.
Known for being durable and long-lasting, this is the same material used in certain types of clothing, pet leashes, and nylon seatbelt. It’s also the same material that the military uses for a number of different components.
Most hiking products feature a waterproof or water-resistant coating that keeps the webbing from absorbing moisture, and the material won’t fade when exposed to sunlight.
Nylon is stronger than Polypropylene in terms of breaking strength and thus is used widely for military applications like Waist belts, backpacks, slings etc.
Nylon webbing is a better choice due to high strength, elongation and softness over Polyester and Polypropylene.
