The weight of the bag depends on what you fill it with.
Upon reception, the base of the bag will be empty and weigh 13 lbs and the top of the bag weighs 17 lbs.
The base of the bag can be filled with water, sand or both, depending on what you're looking for in terms of weight and convenience.
With water, the bag will be around 250 lbs. If the bag is filled with sand, it will weigh around 350 lbs. Filling the bag with both sand and water will weigh up to 450 lbs.
Water is much more convenient, it will be easy to fill, to empty and to move around when needed. However since the bag is lighter with water, it will move during your workouts. To limit movement and get the best experience during your workouts, we recommend filling the bag with sand instead.
