DESIGNED IN THE UK
The Rapz Cobra Bag is the ideal choice for professionals or anyone who wants to take their training to the next level. Made with steel and premium quality leather. All designed with professional fighters and engineers in the United Kingdom.

ZERO STRIKE LAG
The steel spring absorbs almost 100% of the shock from each punch. This means instant swing-back performance, so you're ready to hit again or dodge the Cobra Bag after every strike. Our thick steel shock spring is what allows the bag to accelerate to such high speeds.

360° STRIKE
The Cobra Bag is so much more than just practice for your jabs and hooks; it will test your movement and speed. It is designed to be unpredictable in the way that it swings back after every strike. This will increase reflexes and hand-eye coordination.

ADJUSTABLE HEIGHT
Quickly and easily adjust the height of the Cobra Bag, using the valve. Simply choose your height and twist the valve to lock it in place. This feature makes the Cobra Bag ideal for boxers of all sizes.

ANTI-TIP TECHNOLOGY
Once you have filled the base with sand or water (for outside use), the bag is designed to never tip over or fall. Strike the bag with as much force as you desire. All the energy of every punch is absorbed by our shock spring.

NO FLOOR SCRATCHES
The bottom of the Cobra Bag's base comes with sticky floor grips, which are designed to prevent scratches and marks. Whilst also giving your bag added base strength, so it does not tip over.




FASTER HAND SPEED
The Cobra Bag is unforgiving. It is designed to compel you to either block, dodge or counter punch. Unlike a heavy bag which is completely stationary, the cobra bag will swing aggressively towards you, forcing you to keep punching. This will help activate your fast twitch muscle fibres; increasing hand speed.

DEVASTATING POWER
Heavy bags tend to swing around too much, especially when hitting power shots. The Rapz Cobra Bag is designed to never move from its base position. It is designed to withstand continuous power shots without ever falling, making it much more beneficial to train with.

BOOST IN ENDURANCE
When compared to training with a heavy bag, athletes showed a much higher PPM(punch per minute) average on the cobra bag as it was interacting back with them, forcing them to punch more often. This lead to athletes having much higher endurance when training with a cobra bag.

I purchased this a few weeks ago and have to say it's a great bit of kit. I can already see improvements and great edition to my home gym.
Assembly was quick and easy and have used everyday for the last fortnight!

It was worth the wait, the bag has been sold out for a while now and have been desperate to get my hands on one. Made with very high quality materials and you can tell the design has been well thought through.
I'm a light heavyweight, haven't filled the base yet and the bag is really stable with just the suction cups with heavy striking. So I would definitely recommend it over the others I've tried.

Brilliant bit of kit from RAPZ!
Using the Cobra Reflex Bag to sharpen my hand-eye coordination & work on my combos & they’re getting better & better with every use!
- Nicholas R

I am amazed with the product quality, I was struggling to get the hang of it first and contacted support for help.
They sent me a beginner level spring so the bag is a bit slower and this really helped. I have now gone on to the original spring and have seen my skills really improve. Thanks a lot guys
- Sam L

Very pleased with me Cobra Bag. The increase in speed of my jabs and hooks have already started to show after only a week of use.
Definitely recommend for professionals, this is very hard to get use to at the start. But after you get the hang of it, the benefits start to show!
