When I first tried them on, I found that one of the tie chords in the waist band had disappeared into the waist band. No amount of manipulating could retrieve it. We ended up having to make a small incision in the waist band and get a safety pin into the chord to slowly move the chord towards the eyelet. Once we had succeeded in getting the chord out I tied knots in both ends of the chord to hopefully prevent it happening again.
That said, apart from the inconvenience, the bottoms fit well, are well padded and wouln't have an issue in getting a 2nd pair in the future.
