The XL Tank 4FT Punch Bag: 100kg of Pure Training Power

Some punch bags are built for beginners. Some are built for fitness. And then there's the BULL DOZA™ XL Tank 4FT Punch Bag — built for fighters who want the heaviest, most serious training tool money can buy.

At up to 100kg of capacity, this is not a bag you mess around with. This is a bag you respect.

A Tank in Every Sense of the Word

The XL Tank earns its name. Standing at 122cm (4ft) tall with a 45cm diameter and 141cm circumference, this is a full-size, full-power heavy bag that can take everything you throw at it — and then some.

The exterior is crafted from an ultra-durable thick microfibre skin, reinforced with double stitching throughout and an incredibly strong internal woven lining. Every chain pad features 10 double-locked rivets, and the stainless steel chain setup — four thick chains, two carabiner clips, and a commercial-grade 360° rotating swivel — is built to handle the punishment of serious daily training.

This bag doesn't flex. It doesn't give. It just takes it.

Train With Precision

Built into the design is one of BULL DOZA's signature touches — the bull's face logo with a clearly defined chin. It's not just branding, it's a training tool. Every session, you're targeting the chin, dialling in your hooks, your straight rights, your knockout shots. Train with purpose. Train with intent.

Fill It Your Way — Up to 100kg

The XL Tank arrives unfilled, giving you complete control over the weight and resistance. Fill it with shredded fabric or old clothing for a solid, heavy bag — or go full pro and load it with recycled rubber filler for a dense, firm feel that replicates the resistance of a conditioned opponent.

With a capacity of up to 100kg, you can build this bag to match your exact training needs. Whether you're a boxer, kickboxer, Muay Thai fighter, MMA athlete, or just someone who trains seriously — the Tank delivers.

Built for Every Discipline

The XL Tank isn't limited to one style. It's been designed for boxing, MMA, Muay Thai, kickboxing, karate, taekwondo, and fitness training. Whatever your discipline, whatever your level — if you hit hard and train hard, this bag is ready for you.

With a 4.86-star rating from 22 verified reviews, fighters who've trained on the Tank know exactly what it's capable of.

The Verdict

The BULL DOZA™ XL Tank 4FT Punch Bag is one of the most capable heavy bags on the market. Massive capacity, elite construction, and the flexibility to fill it exactly how you want — this is the bag serious fighters have been waiting for.

Go heavy. Go hard. Go Tank.
