Nylon is the traditional material developed by DuPont over 70 years ago. Nylon is produced in a white color, and can be treated/dyed into any color. Nylon offers the highest initial break strength. It is initially much stronger material than polypropylene or polyethylene. Nylon has two drawbacks: Nylon absorbs water and breaks down in UV light. Although the UV coating helps protect against UV light and water absorption, it is only on the exterior of the net and not in the actual netting fibers themselves. Nylon is by far the strongest material when used indoors, or in a covered practice facility.
