Key Features
What is T-Flex Leather?
T-Flex is a premium high-performance synthetic leather used on commercial combat equipment. It mimics 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, helping minimise moisture build-up and keep gear hygienic through sweaty sessions, while internal foam layers keep the striking surface consistent and comfortable over time.

Frequently Asked Questions (FAQs)
Q: Can I hang the bag from a ceiling mount?
A: Yes - reinforced heavy-duty nylon straps are included for ceiling or beam suspension. Ensure your mounting point is rated for dynamic loads, or use our single or double floor-mounted bag stands.
Q: What's the difference between empty and filled?
A: The empty version ships lighter and lets you customise the fill - grab our Australian-sourced Punch Bag Fill Material (a 4ft takes around 40kg of rag) for a softer bag, or add a sand/fabric mix packed denser at the base for more resistance. The filled version arrives pre-packed at approx. 55-60kg, ready to hang. Want it heavier? We can fill heavier on request - contact us before ordering.
Q: Which size should I choose - 4ft, 5ft or 6ft?
A: The 4ft is the boxing and home-gym favourite - full punching range with easy clearance under standard ceilings. Kickboxers wanting more leg-kick target should look at the 5ft, while Muay Thai and full-range strikers should go the 6ft.
Q: Does it come in other colours?
A: Yes - this bag is also available in white.
Q: Is it suitable for kicks and knees?
A: Yes - the T-Flex exterior handles impact from all angles. At 4ft, hang height determines how much low-kick target you have; for dedicated kick work consider the longer sizes.
