Why can't anyone manufacture a pair of sweatpants with a sensible draw-string?

Question

The workout sweats i bought in the past had a small, thin rope that fell into the fabric or got knotted up beyond recognition. I just bought a new pair made by CHAMPION. Its a continuous loop, Could someone explain to me how to cinch this up & tie it off???
Thanks.

Answer 1

pull it tight, twist up the excess, and tie it off.
