O₃ Modular Cobra Bag Kit (BETA)

The Kewlus Cobra Bag is the world's first modular cobra bag capable of customisations, add-ons, upgrades and DIY integrations. The O₃ features the beautifully handcrafted OctaBase for superior mast rigidity and extra height. Combined with the powerful KS3 Spring, it delivers the speed and performance sought by professional boxers. It includes the Red Bar for increasing the speed even more and the Olympic Sleeve for adding extra rigidity with optional Olympic weight plates. The O₃ features a 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 late September or early October. The first release is a BETA release at a $50 discount, as I hope to get some early feedback. I have been testing prototype versions of these at the local boxing gym and so far have not had any issues - all the boxing coaches and fighters love them. I hope you will too.

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.
• 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. Included are a set of 8 x 2 inch stainless steel screws. The OctaBase is currently not available to purchase separately.

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:

Optional Add-Ons:

• Additional Pair of Kewlus Sandbags (V2): For extra weight and stability, especially if you don't intend on using any Olympic Weight Plates over the top of the first set of sandbags.
• Max Speed Ball & Adapter Combo: Enhance speed training with a lighter and faster ball and adapter combo.
• Cobra Bag Replacement Bladder: Backup replacement bladder for future use.
• For mobility you can attach castor wheels to the back wall of the OctaBase. I designed the back wall to be extra thick for this purpose. Pick up a pair of large castor wheels that don't rotate from your nearest hardware store.
