The Kewlus Cobra Bag Adapter (version 2) is made out of a nylon polymer plastic with outstanding bearing and wear properties. In this second version I have greatly improved the strength, while keeping the weight low.

The adapter has been designed so that the the wide top fits perfectly inside the Kewlus Cobra Bag. The top of the adapter has a flexible, rubbery feel designed to absorb the impact of punches. The neck of the adapter, which slides onto the ClickBar (or 3/4 inch PVC pipe for DIY) has been extended to allow you to adjust the length of the top section.

One key feature of this design is it ensures that the ball remains firm in an upright position rather than flop around like with many other cobra bags.

IMPORTANT: please ensure the ball is inflated properly when training. Punching a poorly inflated ball can cause damage to the adapter.

TIP: For regular intense training wrap a couple of rounds of duct tape around the bottom of the ball to help protect the zip (or laces).

Unbelievable customer service

I had a problem with my adapter. I contacted Kewlus and they more than made things right. I cant believe customer service like this still exists.


This thing works really well. I added this snd a Kewlus bag on another reflex bag I purchased before I found out about Kewlus. I was able to easily modify to work with another pole. Kewlus is superior quality and customer support. I can't say enough about the company. Only bad thing now I wanna scrap or replace the reflex pole and base to get a complete Kewlus setup with V3 spring but its hard to justify the expense with a great hybrid version already working well. From now on only Kewlus when it comes to reflex bags.
