This durable universal weight bag is crafted from 1680D Oxford fabric with PVC coating, making it 300% stronger than most on the market and ensuring both durability and waterproofness. It is designed without fillers and can hold up to a maximum of 37.5 lbs. of weight, including sand, rocks, gravel, snow, dirt, and other contents. Featuring three Velcro fasteners sewn onto the bag, it securely attaches to the frame, providing a tight and firm fit. Quick and easy to use, simply fill the anchors with sand through the large top opening and attach the "hook and loop" straps to the canopy legs. This weight bag effectively stabilizes any instant canopy, pop-up tent, camping sun shelters, or sports umbrellas. Size: extra large. Color: Black.
