Seems very sturdy
Made of good material, good and sturdy. My son fits his bowling shoes, 10 lb ball and wrist brace with space to spare.
My niece lived her bag. I bought it for her because she does bowling as part of her special needs socializing group.
It did it’s job by holding my ball. It seemed a little to big for a bowling ball which made it just roll around in the trunk of the car when I was driving.
Bowling bag arrived next day ball and shoes fit great.
