Secure your outdoor setups against unpredictable winds with this set of four heavy-duty sandbags, engineered to provide maximum stability for garden tents, gazebos, and patio umbrellas. Each bag is meticulously hand-sewn from premium 600D Oxford fabric, a high-density material renowned for its exceptional resistance to abrasions, tears, and harsh weather conditions. Designed for versatility, these weights feature a generous capacity of up to 16 kg per bag when filled with sand, gravel, soil, or stones, allowing you to customize the ballast according to your specific environment. The integrated double Velcro locking system ensures a rock-solid attachment to any structure leg without the need for tools, making setup and breakdown fast and intuitive during camping trips, festivals, or backyard celebrations.

By utilizing a secure hook-and-loop closure, the bags prevent leaks and shifting, maintaining a low center of gravity that keeps your equipment anchored.
