This four-piece canopy counterweight bag is made of military-grade 1680D PVC-coated polyester fabric, which is waterproof, sun-resistant and has a tear resistance three times that of ordinary sandbags. It remains as tough as new even in heavy rain and scorching sun. Each bag can hold 30 pounds of on-site sand, gravel and soil for on-site weight gain, and the total weight can easily exceed 120 pounds, providing rock-solid wind-resistant support for large tents, party tents and beach sunshades. The unique four-sided high-strength Velcro and widened handle design can firmly embrace any thickness of the support legs with just a twist and press. No tools are needed, and it can be installed and removed instantly, completely saying goodbye to the embarrassment of zipper jamming and breaking. The bag opening is equipped with a double PVC anti-seepage coating and reinforced stitching for double protection, ensuring that fine sand does not seep in and rainwater does not seep in. After storage, it is only the size of a palm and its weight is almost negligible. It does not take up much space when carried in a vehicle. Whether it's weekend camping, lawn wedding, car rear party, outdoor market or seaside barbecue, just fill it up and tie it up casually, and the tent will remain as stable as a mountain in the fierce wind and rain, truly allowing you to "stay stable wherever you go", saving you time, effort and space. Color: Pink.
