We have rounded the edges and glued the patch on a used children ski pants. He now holds well and is serving. The child plays outside with the snow pants, but the actual skiing we still have another pants. The patch was therefore not subjected to "acid test", but the pants is at least as reasonably tight again, play for an hour or two outside it fits anyway. When I read the other reviews so I have the impression that these patches are actually specially designed for rain and snow pants, as they seem to be less good at keeping in Jeans o. Ä.. We were specifically looking for a solution to the hole in the ski pants, we are very satisfied.
