It is the sound every player lives for: the distinct thwack of a high-velocity shot hitting the back of the net. But have you ever considered what that net is actually made of? While the steel frame of a goal gets all the glory, the mesh is doing the heavy lifting, absorbing thousands of pounds of force over a season. Choosing between nylon and polyester isn't just a technicality—it is the difference between a net that lasts for years and one that rots away after a single rainy spring. If you want to stop replacing your mesh every six months, you need to understand the science behind the fibers.
The Battle of the Fibers: Nylon vs. PolyesterNylon has long been the traditional choice for lacrosse netting because of its incredible tensile strength and elasticity. It "gives" when hit, which helps absorb the impact of a 90 mph shot. However, nylon has a major weakness: it is hydrophilic, meaning it absorbs water. When a nylon net gets wet, it stretches, sags, and becomes heavy. Over time, repeated moisture exposure and sun damage (UV rays) cause nylon to become brittle and yellow.
Polyester, on the other hand, is the modern standard for high-end field lacrosse nets. Unlike nylon, polyester is naturally hydrophobic; it sheds water rather than soaking it up. This means your net stays the same weight and tension whether it’s a humid morning or a torrential downpour. Most importantly, polyester has superior UV resistance, making it the go-to material for field lacrosse goals that sit out in the sun all year long.
Thickness and DurabilityRegardless of the material, the thickness of the twine—measured in millimeters (mm)—is the primary indicator of a net's lifespan.
2.5mm to 3.5mm: Best for backyard use or light youth practice.
4mm to 5mm: The standard for high school and collegiate programs.
6mm to 7mm: Professional-grade "monster" nets designed to withstand elite-level shooters.
For those playing the indoor game, durability is even more crucial. Specialized box lacrosse nets are almost always made of heavy-duty, weather-treated materials because the 4x4 box lacrosse goals take a much higher volume of shots in a smaller surface area. Whether you are outfitting a stadium or a set of box lacrosse goals, opting for a higher mm count in polyester will always yield a better return on investment.
Weather Treatment: The Final LayerThe best nets go a step beyond the base material by adding a weather-protective coating. This resin or UV-inhibitor bath prevents the fibers from breaking down at a molecular level. When you invest in premium field lacrosse nets, you aren't just buying rope; you are buying a engineered barrier against the elements.
Yes, polyester typically resists UV and moisture better, helping extend outdoor lifespan.
Generally, no. However, white nets may show yellowing from UV damage more quickly than black or colored nets, which can help you identify when it is time for a replacement.
Check for "shedding" (small fibers coming off the twine) or a stiff, crunchy feel. If the net feels brittle or loses its stretch, the UV rays have compromised the material integrity.
They can absorb water and stretch slightly unless specially treated.
In an outdoor environment, a high-quality polyester net will typically last 1 to 2 seasons longer than an untreated nylon net of the same thickness.
