Train like a champion with the O₃ Cobra Bag, the world's first modular reflex punching bag. Featuring the beautifully handcrafted OctaBase for superior stability and powered by the renowned KS3 Spring, the O₃ offers unmatched performance and extra height without the hassle of creating your own base. It includes the Red Bar for increasing the speed and the Olympic Sleeve for adding extra rigidity with one or two Olympic weight plates. It also features the Stainless Steel Mast to be able to handle regular intense training. Previously available only as a custom setup for professional boxers and elite boxing gyms, the O₃ Cobra Bag now brings professional-grade training to you!

Please note that the O₃ is due for release in August, possibly earlier. Click on the Notify button to receive a notification email when it becomes available.

What's Included:

  • KS3 Spring: Third generation spring with multiple setup options.
  • Leather Cobra Bag Ball: Durable leather ball for powerful punches.
  • Cobra Ball Adapter (V2): Extendable length for increased reach.
  • 2 x Click Bars: Lightweight, rust-free aluminum bars.
  • Stainless Steel Mast: Made for the ultimate strength and reliability.
  • Red Bar: Increase the speed of your cobra bag by switching the Click Bar to the Red Bar in the top section.
  • Base Connector: Versatile base connector made from composite fiber.
  • Platform Paddles (V2): Wider and stronger for a stable base platform.
  • Pair of Sandbags: Designed for stability when filled with sand. I recommend grabbing an extra pair (optional) for double the weight and increased performance.
  • Olympic Weight Plate Sleeve: Add extra rigidity to your base for even better performance with one or two weight plates on top of the sandbags. The Sleeve slides onto the Mast and your weight plate slides onto the Sleeve.
  • OctaBase: Handcrafted, octagonal plywood base that combes the old-school beauty of wood with the strength of multi-layered ply, offering superior rigidity as well as extra 5 inches of height over the Paddles.

Height Range:

5'1" to 6'0" (155 cm to 183 cm). Convertible to a shorter form for children.

Setting the correct height for you is important. The top of the ball should be just above your chin. Watch boxing coach Paul Briggs (former highly ranked contender in the light heavyweight division) explain how to set the correct height:
