Our bag is built for those who demand the best from their training - whether you're a professional fighter or pushing your limits in the gym. Engineered in the United Kingdom with input from elite athletes and expert engineers, it combines high-grade steel with premium leather for unmatched durability, responsiveness, and precision. Designed to withstand intense training, this bag delivers the speed, power, and reflex development you need to train like the pros.

ZERO STRIKE LAG
Experience lightning-fast rebound with every strike. Our bag's high-tension steel spring absorbs nearly 100% of the impact, delivering instant swing-back action for non-stop training. Designed for elite performance, its heavy-duty steel shock spring generates extreme acceleration, making every session sharper, faster, and more dynamic. Train smarter, react quicker, and dominate every exchange.

360° STRIKE
The Rapz Cobra Speed Bag is far more than just a tool for practicing jabs and hooks, it challenges your movement, speed, and reaction time. Engineered for unpredictability, it rebounds in unexpected directions after every strike, forcing you to stay sharp and adapt quickly. This dynamic movement enhances reflexes, hand-eye coordination, and defensive skills, making it an essential training tool for any serious athlete.

ADJUSTABLE HEIGHT
Easily customise the height of the bag with a simple twist of the valve. Adjust it to your perfect level and lock it securely in place within seconds. This adaptable design makes it the ideal training tool for fighters of all sizes, ensuring a personalised and effective workout every time.

ANTI-TIP TECHNOLOGY
Once the base is filled with sand or water, our bag is built for complete stability - no tipping, no falling. Designed to handle the hardest strikes, it stays firmly in place while the high-tension shock spring absorbs impact, ensuring smooth, realistic rebounds with every punch. Train with full power and confidence.

NO FLOOR SCRATCHES
The base features sticky floor grips, designed to protect your floors from scratches and marks while enhancing overall stability. These grips keep the bag firmly anchored, allowing you to train harder without worrying about movement or tipping - no distractions, just pure performance.
