Why do my leggings keep getting holes in the crotch?

[Nativity3]

It's sort of to the side (usually at the top of one leg). I am guessing it's where my legs rub?

Anyway to prevent it?

I think it's just that's where the pressure point is when they are stretched by pulling them on. Plus, clothes are not always made especially well or with the best materials.

Better quality might work.
