Ripped after a few months

We were very disappointed with these pants. They ripped after only a few months. When I say ripped, I mean that he pulled them out of his suitcase and there was a ten inch rip from the back pocket all the way down the rear end. Strangely, we have no idea when or how they ripped. I suppose there is some slight chance that the baggage handlers ripped them, but I seriously doubt it. It is still a mystery.With Amazon, you can't really take them back to the store and complain. We threw them away. It is very sad because they were nice pants with a very light wool fabric. He wore them to dinners and such, but not often since he is more of jeans and t-shirts type of guy.
