Event planners and outdoor enthusiasts, these CROWN SHADES sand bags will keep your canopy from becoming a runaway kite! The package includes 4 unfilled bags made from durable PE-coated Oxford fabric that's both waterproof and sand-proof. Each bag can hold up to 37.5 pounds (150 pounds total for all four), giving you serious wind protection for pop-up tents, gazebos, and outdoor structures. The three Velcro straps secure tightly to tent legs without damaging them, while the reinforced stitching ensures they won't burst under pressure. The carry handles make transportation easy, and the sleek black color looks professional at any event. Filling is simple - use sand, gravel, stones, or even bottled water (though not liquids directly). When you're done, just empty them and they store flat, ready for your next outing. The universal design works on any surface - grass, pavement, beach, you name it. Whether you're setting up at markets, festivals, sports events, or backyard parties, these weights provide the stability you need when the wind picks up. Seriously, if you've ever chased a flying canopy across a field, you know these sand bags are worth their weight in gold for preventing disaster and keeping your setup secure!
