The Vevor workout sandbag is built for strength training, conditioning, and full-body workouts at home, in the gym, or outdoors. It features a durable polyester Cordura 1000D inner bag with PVC coating and a nylon 1050D Cordura outer bag for added toughness. The adjustable design supports weight ranges from 50-125 lbs to suit different training levels and exercise goals. Waterproof construction, reinforced seams, and secure closures help prevent sand leakage during intense use. Full-length handles make it easy to lift, carry, slam, and store.
