    Seems sturdy and very well made
  

*by R***A on Reviewed in the United States on 10 April 2017*

Seems sturdy and very well made. Everything about it looks like it'll last for quite a while. It's perfect for travelling athletes as you can empty out the sand and refill it, so no heavy items to check in.The one problem is the belt. The belt is sturdy, but too big to fit me snugly. I have a 32inch waist and the loop is under the strap when pulled tight, the velcro keeps it attached, but there's a gap and doesn't sit as snugly as you'd want. Skinny kids might have a bit more of a problem.
