KS3 Cobra Bag - Freestanding

The Kewlus Cobra Bag is the world's first modular cobra bag. Now with the third generation KS3 Spring it can be set up for both adults and small children, giving everyone the same great boxing reflex training.

The Freestanding Cobra Bag includes a set of the Platform Paddles and a pair of Sandbags so you can get started quickly. You just have to connect the Paddles to the Multi Base, fill the two sandbags with sand and you can start training.

Once you become familiar with the basic setup, check out the Assembly and Optimisation page to see how you can get even more from your Kewlus Cobra Bag.

Advanced Setup Used By Professional Boxers

The Advanced Base Setup is the one mostly used by professional boxers like Tim Tszyu, the Irish Champions, Aaron and Stevie McKenna, and others. It involves making a multi-layered MDF board base instead of using the Platform Paddles. If you choose to set it up this way, then grab the KS3 Cobra Bag - Core Only with a set of Sandbags. For extra speed and rigidity, grab the Red Bar and the Olympic Sleeve as well.

Please note that you can always start with the Freestanding unit to get going quickly and upgrade to the advanced setup at a later stage.

What's Included

These are the components included with the KS3 Boxing Cobra Bag:

• Kewlus Spring (KS3) is the 3rd generation Kewlus spring that can be setup in multiple ways, including plugging directly into the Base to be used by smaller children.
• Max Power Genuine Leather Cobra Bag Ball is made from genuine leather, designed to handle the most powerful punches and combos;
• Kewlus Cobra Ball Adapters (V2), designed to be used with most speed balls but is the perfect match for the Kewlus Balls. One unique feature that's not found on other cobra bags is it allows the user to extend the length of the top section, thus increasing the reach of the cobra bag;
• 2 x Kewlus Click Bars - one above the spring and one below. These are made from light, yet strong aluminium which will not rust, with dual push buttons at each end. They are a key part of the modular click-and-go system;
• Kewlus Click Mast (V2) - designed to simply click into the Multi Base for quick and easy removal and storage of the cobra bag. Made out of strong aluminium it will never rust. The bottom Click Bar simply slips into this mast and clicks in place at the desired height, giving you a height adjustable cobra bag suitable for both kids as young as 8 and adults as tall as 6 foot. Make sure to use the stainless steel hose clamp that comes with the Base to lock it in place;
• Kewlus Multi Base - super strong, minimalistic base made from composite fibre. It's designed to be used in multiple ways, such as with a baseboard, with Platform Paddles, with Suction Cup Handles or simply bolted to the floor. It comes with a stainless steel clamp for the collar to lock the mast in place for the ultimate rigidity.
• Platform Paddles (V2) - these second generation Paddles are now wider and stronger. They come with 4 screws to screw them into the Multi Base and most importantly a central locking screw and nut to lock them all together at the center of the base.
• Kewlus Sandbags - these come as a set of 2, and are specifically designed to have the right capacity, so that when fully filled with sand or gravel they will give you enough weight for a stable platform. For extra weight I recommend using a plastic bag liner and filling them with wet sand.

Height Range

The height range of the cobra bag is roughly 4'8 (143 cm) - 5'7 (171 cm) from the floor to the top of the bag. If you wish to increase the height, consider making a 5-inch tall "Stubby" baseboard (see details and video: https://kewlus.com/blogs/diy/how-to-make-baseboard-cobra-bag).

Convertible To Short Form

The KS3 Boxing Cobra Bag can be converted to a shortened form (KS3 Spring plugged directly into the Multi Base), making the height range roughly 3'3 (100 cm) - 3'7 (110 cm). The shortened form is ideal for smaller children or for mounting upside-down from the ceiling or horizontally on a wall.

Optional Accessories & Add-Ons

Check out the Accessories section for optional accessories and add-ons such as:

• Max Speed Cobra Ball & Adapter Combo - switch to a lighter and faster ball mid-session;
• Genuine Leather Boxing Gloves - grab a pair of these genuine leather boxing gloves to get the most from your cobra bag training sessions;
• Hand Wraps - use a pair of handwraps to absorb the sweat and protect not just your hands, but your gloves as well.
• Suction Cups (Limited/Varied Usage) - these come as a pair and can be used on painted concrete flooring, such as in a garage to hold down the Base as a possible alternative to the Platform Paddles. They can be also used for mounting the shortened version of the cobra bag on a vertical surface. Please note that these suctions cups do not work on all surfaces, and even on smooth tiles are likely to dislodge with heavy punches. I cannot guarantee that they will work on the surface that you choose. Failure to stick to your floor or wall surface does not qualify for a refund. See the Suction Cups product page for set-up instructions and a demonstration video.
