Purchased these about two months ago and, so far, they have held up well. After many trips through the washing machine, they are still soft, comfortable, and in great shape. No noticeable changes to the elasticity, or the fabric. My only complaint is that they do tend to bunch up inside the thigh area. I don't know if this is because of the inseam length, or the lack of a substantial elastic on the leg openings. I prefer this length, and other brands I wear don't seem to bunch up the way these do.

This is unrelated to product quality, but still worth mentioning. The packaging with these is unbelievably excessive. Each pair is in it's own box, and all are packaged in a single, larger box. I understand this is a trend in product packaging that is somehow supposed to provide a sense of quality, but really, all it does is remind me that the company spends a lot of money on what is essentially garbage. Over-designing the package doesn't improve the product quality.  I probably won't buy these again for this reason. There are a million underwear companies out there, whose quality is better, and whose product comes in a less excessive package.
