Query: flawed drawstring

These sweats have a simple flaw: if the end of the drawstring gets pulled into the waistband (say, during washing), they're ruined. There is no way get the end back out so you can tie them and there isn't even a knot to prevent this from happening. Unless you want to tear them apart yourself, they're now only good for washing windows and drying dishes.
