These are good quality linen pants; they are too long. That's slightly annoying as the maker certainly could have done a better job estimating leg length. I had to have the legs shortened. But they came out very nicely and are good quality for the price. Just think of them as coming unhemmed and reconcile yourself to spending to have them tailored unless you are very tall for your waist size.
