Overview

The 28” 100 lb. Aqua Training Bag® Brawler Haymaker Black is built for fighters who like to mix precision and power. Its longer, cylindrical shape offers an extended striking surface, making it ideal for practicing body shots, uppercuts, and full-range combinations. Compact enough to move easily, yet heavy enough to take a beating — this is the go-anywhere, hit-anything bag for serious training.

28” 100 lb. Aqua Training Bag® Brawler Bag FEATURES:

DESIGNED FOR VERSATILE STRIKING — Whether you’re a boxer, MMA fighter, or fitness enthusiast, the Brawler Bag’s longer profile gives you more realistic target zones for head-to-body combinations and striking from different angles.
HAND-CRAFTED COLOR FINISHES — Each Aqua Training Bag is hand-swirled with a unique color pattern, so no two are ever the same. Eye-catching, durable, and made to stand out in any gym.
WATER-FILLED IMPACT TECHNOLOGY — The fluid core absorbs punches and kicks better than traditional heavy bags, reducing strain on your joints while giving you the feedback of a real opponent.
BUILT TO LAST — Constructed in the USA from thick-walled vinyl with injection-molded ends, the Brawler Bag is UV-resistant, waterproof, and made to handle years of heavy training — indoors or outdoors.
PORTABLE & PRACTICAL — Weighing only 13 lbs. unfilled, it’s easy to move, hang, and set up anywhere. Once filled, its 100 lb. weight provides a solid, realistic feel that’s perfect for both gym and home use.

FAQ'S

Please read our FAQs page to find out more.

How to fill your Aqua Training Bag

1. Remove the valve plug with a Phillips head screwdriver.

2. Connect the hose-filling attachment to your hose.

3. Before starting the water, place the tip of the hose attachment into the hole of the Head Hunter Slip Ball.

4. When you have filled the desired amount of water, shut the water off and remove the hose attachment.

5. Place the valve plug back into the bag and tighten with the Phillips head screwdriver until snug.

6. Top off head with air using an air pump that has a needle.

What's the correct hanging height for the Aqua Bag?

A good starting point is to hang the bag so the equator (the widest middle point) sits at 5'2" from the floor. This works for most average-height users. For group or commercial gym settings, you may want to vary heights across bags to accommodate different user heights. Leave 3–4 feet of space between bags when setting up multiple units.

What size Aqua Punching Bag should I get?

The right size depends on your experience level, training goals, and available space. The 15" 75 lb bag is ideal for beginners, younger athletes, speed and cardio work, or anyone looking for a lighter, more responsive feel. The 18" 120 lb bag is the most popular choice — it suits intermediate to advanced boxers, MMA fighters, and serious fitness enthusiasts who want a versatile all-around bag. The 21" 190 lb bag is our largest option, built for maximum power training, professional fighters, and commercial gym settings where the bag needs to handle heavy, high-volume use. When in doubt, the 18" 120 lb is the go-to for most athletes.

What's included in the box?

Every Aqua Punching Bag ships with everything you need to get it set up: a compressed Aqua Punching Bag, a shackle for hanging, a hose-filling nozzle, and an extra stopper. Please note that hanging chains and a mounting system are sold separately.
