The ONEX Power Bag is the cheapest thing in this guide at £16.99 — a filled sandbag with padded strap handles, sold for MMA, weightlifting, running and full-body workouts. It holds a 4.1 rating from 315 Amazon ratings and sits 14th in Amazon's Fitness Weights category. What puts it at #10 rather than higher is what its own listing says about itself.

The title advertises a 5-30kg range, the size field says 5kg and the weight field says 5 Kilograms — three different answers to how much you are getting, and none of them match the buyer who put the delivered bag on the scales and got 19.98 kg. It is also sold as a "Weighted Slam Bag", yet one of its own bullets asks you not to throw it on the floor, warning that the sand inside will press outwards and the bag will blast. Every claim on this page comes from the Amazon listing and its customer reviews — we have not tested this bag ourselves.

## Questions people ask

**What weight arrives with the ONEX Power Bag?**

The listing does not say clearly. The title offers a 5-30kg range, while the size field reads 5kg and the weight field reads 5 Kilograms; a customer review reports a delivered bag weighing 19.98 kg on the scales.

**Can I slam the ONEX Power Bag on the floor?**

The listing itself says no: it states the bag is made of soft material with sand filling inside, and that throwing it on the floor with force puts great pressure from inside and the bag will blast.

**What is the ONEX Power Bag made of?**

The specification table lists PU Leather. A bullet on the same listing calls it fabric, and a customer review describes it as PVC coated — the advert does not settle which it is.

**Does the ONEX Power Bag come with sand?**

Not stated. The listing says the bag is filled with sand or cloth pieces, but the included components field lists only "power bag", so the advert never confirms whether it ships filled.

**How big is the ONEX Power Bag?**

Package dimensions are listed as 75 x 23 x 23 cm at 5 kg, and one review describes it as compact enough for easy storage but wide enough to hug comfortably for squats or sit-ups.

**Who is the ONEX Power Bag aimed at?**

The listing names MMA, weightlifting, running, powerlifting and full-body workouts, and claims it suits both home and commercial gyms. It is listed as a unisex product.
