The Spartner can be attached to a boxing bag very simply.

Our bearing swivel enables quick and effortless rotation of the bag when hit or pushed off center, allowing the weighted foam balls to swing up and fight back.

Because of The Spartner’s design, the movements of the balls are always random and difficult to learn, offering the most lifelike combat experience you can get without an actual sparring partner.


Early design involvement with the multi award-winning product design agency Design Partners based in Bray, Co. Wicklow. We have gone for a sharp timeless design that integrates features common in combat sports gear and apparel.

The main strap, arm straps, leather, webbing and carry bag are made to last with the finest quality genuine cowhide Italian leather and seat belt grade nylon webbing. All these components are hand stitched in Ireland by the multi award-winning, sustainable bag manufacturers Mamukko based in Kinsale, Co. Cork.


In these videos we go through a few options for setting up and using your Spartner, just to get you started.

Setting up & using the Spartner.

For clarity, there is no boxing bag included with this – The Spartner attaches to an existing bag. Make sure your bag is far enough away from walls and stands to allow it to spin freely and put up a good fight, and that you have a standard diameter boxing bag 12″-16″, as this version of the Spartner will not wrap around a larger diameter heavy bag.
