About MaxxMMA 3ft Patented Water/Air Boxing Bag Shell - Black
Feel every strike. Control every round.
A patented water-and-air heavy bag designed to deliver responsive impact feel, adjustable training weight and compact performance for boxing, kickboxing and MMA workouts.

Responsive impact—not a rigid bag of sand
The internal water/air bladder and SOFTSTRIKE™ construction create controlled give on contact. Water movement also adds a shifting response that makes balance and strike recovery part of every combination.
Engineered to move with the impact
Unlike a conventional densely packed bag, the internal water shifts as you strike while the air helps tune the bag’s response and maintain its shape.
Water-Driven Resistance
Adjust the water volume to set the training weight within the supported 70–120 lb range.
Air-Tuned Hand Feel
Use the air chamber to refine firmness after filling, following the supplied setup instructions.
Natural Movement
The shifting water introduces movement that encourages stable footwork, balance and controlled follow-through.

One bag. Multiple disciplines.
The compact 3-foot format supports a wide range of upper-body striking work when installed at the correct training height.
Power & Combinations
Practice straight punches, hooks, body shots and combination flow against adjustable resistance.
Mixed Striking Drills
Build striking rounds around punches, elbows and controlled close-range work.
Upper-Level Kicks
Use the compact target for controlled kicks within the bag’s installed strike zone.
Cardio Conditioning
Create timed rounds that combine movement, coordination and high-energy striking.

Adjust the weight as your training progresses
The bag ships unfilled, allowing you to set the water volume for your preferred resistance and then add air as directed to shape and tune the strike feel.
Supported adjustable filled-weight range. Always verify that your ceiling mount and surrounding structure are rated for the selected working load.

Frequently asked questions
Essential information for setup, filling and everyday training.
Does the MaxxMMA bag arrive filled?
No. It ships unfilled, making it easier to transport and allowing you to select the preferred training weight during setup.
What is the adjustable filled-weight range?
The supported adjustable range is 70–120 lb, approximately 31.8–54.4 kg.
How large is the bag?
The manufacturer specification is approximately 37 inches long and 13 inches in diameter, commonly described as a 3-foot heavy bag.
What does SOFTSTRIKE™ technology do?
It combines a water/air bladder with the bag construction to produce a more responsive impact feel than a conventionally packed rigid heavy bag.
Can I adjust how the bag feels?
Yes. The water volume determines much of the total weight, while the air chamber helps shape and tune firmness. Follow the supplied filling instructions and stay within the supported range.
Is a ceiling mount included?
A ceiling bracket or structural mounting hardware is not listed among the confirmed package contents. Choose properly rated mounting hardware for your structure and selected filled weight.
Which training styles is it suitable for?
The compact bag is suitable for boxing, MMA, kickboxing and fitness striking drills within its installed target zone.
Can it be used outdoors?
For longevity, use and store the bag in a suitable protected training area. Avoid sharp objects, hot surfaces, prolonged direct sun and environments that may freeze the water.
What should I check before training?
Inspect the mounting point, hanging straps, seams and shell before each session. Stop using the bag if any component appears damaged or insecure.
