Query: no good for big bellies

It's excellent, I use it very often - bike riding, exercising, for walks with my dog. It even has a little pocket for anything small you might wanna carry with you, i.e. money, keys. The only disadvantage is the buckle is not firmly attached to the belt so it can slip. Too bad if your waist is wider then average, it doesn't stay in place and simply falls out. I tried to wear it over my jumper which enlarged my waist and it wouldn't hold.
