The SBRX Black empty punching bag is designed for those who want complete control over their training . The bag is self-loading, so you can precisely adjust the weight and hardness that is ideal for you - whether it's technical work, strength development or intense combinations.

The outer cover is made of durable REXION synthetic leather , which is highly resistant to cracking, abrasion and repeated high-impact impacts. The 6 mm thick EVA foam placed under the cover ensures that the bag provides a flexible, pleasant contact even when fully inflated, reducing the strain on the joints.

One of the most important structural elements of the bag is the built-in steel reinforcement ring , which runs along the entire perimeter. Thanks to this, the punching bag retains its shape during training, the filling is evenly distributed, and no “dead spaces” or deformations develop. This is especially important for intense kicks and powerful combinations.

The bottom attachment point allows for additional stabilization of the bag, providing more controlled movement, making it ideal for club training and advanced athletes. The empty design has the advantage of being more convenient to transport, while the end result is a fully customized premium training tool.

The SBRX Black is the perfect choice for gyms, clubs and demanding athletes looking for a long-term, reliable, stable and professional quality punching bag.
