Portabrace sandbags are carefully designed and manufactured using the same production process and materials as our renowned camera cases. The sandbags are constructed with highly durable 1000-denier Cordura® fabric and a robust nylon strap. Double stitching ensures additional strength and lasting value. The interior sand pockets are made from a unique semi-flexible material that prevents tears and sand leaks. There is an integrated nylon carrying handle as well as a large steel hook and ring that allow you to securely wrap the sandbag around C-stand legs, tripod legs, attach it to equipment cases or secure it to lighting stands. The SAN-40XLB can hold up to 40 lbs (18 kg) of sand Dimensions Exterior: 29" x 13" / 73.66 x 33.02 cm
