Onyx Wrecking Ball Boxing Bag

Onyx Wrecking Ball Boxing Bag

Premium Combat Gear. Built for Power, Designed to Endure.

Seventy kilograms packed into a 70cm sphere - the Onyx Wrecking Ball is the densest bag in our range, and that density is the training tool. Hung at head height, its compact round form gives you nothing to hide behind: hooks curve around it, uppercuts drive up into it, and its short, heavy swing forces you to slip, roll and counter like you're working a live opponent's head.

Made from premium T-Flex leather with a heavy-duty metal chain suspension, it's built to endure years of close-range power work in commercial gyms, boxing clubs and fight studios.

Empty or Filled - Your Choice

• Empty - cheapest to ship; fill it yourself with a sand core and rags/foam mix (see our bag fill material)
• Filled - arrives ready to hang at approx. 70kg
• Custom fill weights - we fill in-house at our Sydney warehouse; get in touch for your target weight

• 70 x 70 x 70cm, approx. 70kg filled - compact but seriously heavy for a short, punishing swing

What is T-Flex Leather?

T-Flex leather is a premium, high-performance engineered leather used on commercial combat sports equipment - the look and feel of genuine leather with added durability, impact-tested to withstand up to 300,000 strikes.

It's also UV-resistant, water-resistant and nano-antibacterial, staying supple while holding shape, with internal foaming layers for a consistent striking surface over time.

Designed in Australia by Fitness Hero

Every Onyx bag is designed in Australia and specced for Australian gyms - stocked and filled at our Sydney warehouse, backed by local warranty support, and you can see the Onyx range in person at our Bankstown Megastore. When you buy Onyx, the people who designed it are the ones who answer the phone.

Frequently Asked Questions (FAQs)

Q: What makes a wrecking ball bag unique?
A: Density and shape. Packing ~70kg into a 70cm sphere gives a short, heavy swing that punishes lazy feet, while the round profile invites hooks, uppercuts and angled shots a straight bag can't take properly. It's the closest a bag gets to working an opponent's head.

Q: Does the bag include chains?
A: Yes - a heavy-duty steel chain assembly with D-ring attachments, ready to hang. Add our 360 rotating swivel (rated 350kg) to protect your mount from the twisting a 70kg ball generates.

Q: What can I hang 70kg from?
A: A structural beam or rated ceiling fixing, our wall mounted bag arm or modular bag racks - all comfortably rated for it. If in doubt about your ceiling, ask us first.

Q: Which Onyx bag is right for me?
A: Straight 4-6ft bags are the all-rounders; teardrops for knees and clinch; the T-shape for uppercut wings; the 2-in-1 torso for ground work - and the wrecking ball when your focus is head-height power and movement.

Q: Can I fill it with sand?
A: Yes - it's designed for sand filling. Or have us fill it to your exact target weight at our Sydney warehouse before dispatch.
