Incredible versatility and performance. No other adjustable sandbag provides greater training versatility. Each AlterForce sandbag has the capacity to accommodate 4 pre-filled filler bags in predetermined weights to create 4 different effective training weights per bag. Unlike other adjustable bags that are filled with pods that can shift throughout the bag and creates lumps, these filler bags are evenly-weighted throughout a tube that extends the length of the bag for optimal distribution, regardless of how many filler bags are used. Zippered end provides easy access to filler bags.

Multiple handle configurations ensure proper grip alignment for any sandbag exercise from slams, carries, cleans, presses, and more. Neoprene filler bags can be used individually for carries or added resistance to bodyweight movements like squats, pull-ups, and more. Bags ship prefilled.

Durability. As our most durable adjustable sandbags, they're made with tear-resistant vinyl with triple-stitched seams so they hold up to heavy use. The cover is incredibly easy to clean since it's naturally moisture-resistant. Multiple high-quality ergonomic handles provide a great grip and accommodate various workouts.
