Our products feature high quality materials using the latest technologies to ensure our consumers" safety.Our high-quality nets have many features that our competitors simply cannot match:* Made of durable Polyuthylene (PE) material: UV-coating adheres better to PE than the polyester nets of our competitors, making ours last longer. Even if polyester and PE had the same density, PE would last longer because of better UV-protective adherence. * Our nets are stronger and denser: all plastic is made from resin, so the denser the net, the more resin per square foot. This is more expensive, but it creates a harder and stronger net for your children"s safety. * Anti-Fungal/Anti-Bacterial Coating. * UV-Protecting Coating. * Zipper Doors: extra security straps that buckle to avoid accidental openings. * Reinforced stitching on straps and doors (3 rows vs. 2 rows of competitors) for better durability and safety.
