Onyx T-Shaped Boxing Bag Premium Combat Gear. Built for Power, Designed to Endure. The T-shape exists to solve a problem every straight bag has: no realistic targets for uppercuts and body hooks. The widened upper wings of the Onyx T-Shaped Boxing Bag give you head-height targets to hook around and drive uppercuts into, while the slimmer body section takes straight punches and body shots - so full combinations flow on one bag the way they do in a fight. Standing 135cm tall and weighing approximately 40-50kg filled, it's constructed from premium T-Flex leather with triple-stitched seams and impact-absorbing inner layers, hung from a heavy-duty chain assembly. Built for boxing, Muay Thai and MMA striking drills in commercial gyms, studios and serious home setups.

T-Flex leather is a premium, high-performance engineered leather used on commercial combat sports equipment. It mimics the look and feel of genuine leather with added durability for heavy training - impact-tested to withstand up to 300,000 strikes. It's also UV-resistant (reduces fading and ageing), water-resistant and nano-antibacterial, minimising moisture build-up and keeping gear more hygienic through sweaty sessions. The material stays supple while holding shape, and the internal foaming layers replicate the cushioning of a natural oil-layer finish for a consistent striking surface over time.

Head-and-body combinations flow naturally on one bag. Q: Should I buy it empty or filled?A: Filled arrives ready to hang at approx. 40-50kg. Empty ships cheaper and lets you control the weight and feel - use a sand core with a rags/foam mix, or grab our bag fill material. Want a specific weight? We fill in-house in Sydney - contact us for a custom fill. Q: Does it include chains?A: Yes - a heavy-duty steel chain suspension system comes included, ready for installation. Pair it with our 360 rotating swivel to protect your mount and keep the bag hanging true. Q: What can I hang it from?A: At 40-50kg it's well within the rating of our wall mounted bag arm or modular bag racks, or any ceiling fixing rated for a swinging heavy bag. Q: Is it suitable for both boxing and MMA?A: Absolutely - the shape supports striking drills, clinch work and body-shot conditioning across disciplines.
