FAQ
What is the best material to fill the bag?
We recommend a mix of sand and shredded fabric or cotton to achieve a balanced feel. Avoid using only sand as it can make the bag too rigid.
Can the bag be used outdoors?
The PU leather is weather‑resistant, but prolonged exposure to rain or direct sunlight may degrade the material. Use a protective cover for outdoor storage.
How do I adjust the firmness after filling?
Simply add or remove filler material through the zippered opening. The bag’s design allows easy access without compromising the outer shell.
Is the bag suitable for children?
The bag is designed for adult use due to its size and weight. For younger users, we recommend a smaller, lighter bag.
What is included in the 6‑in‑1 set?
The set contains one 4ft unfilled punching bag, a pair of 12 oz boxing gloves, hand wraps, a jump rope, a grip enhancer, and a set of two reflex balls.
