I own several pairs of these in 33x36, and they are great. My favorites, in fact. But, as the title says, the legs twisted with the first washing. And I didn't even dry them on high, like I usually do. Also, the leg openings seem a little larger, and the fabric a little thinner than my others.

Sending them back.

Edit, 05/11/15:
Have since ordered more. All have been fine. The leg seams twisted a tiny bit on a couple pair, but still perfectly acceptable.

I really made this edit to point out one caveat:
The top corners of the pockets are very stiff, and "work" the softer fabric they are sewn to, eventually causing holes. If you wash them frequently, holes will develop there before anything else wears out. This has always been the case with this model.

Other than that, I like these jeans. The small leg opening makes them perfect for bicycle riding (stays off of chain). The generous fit is also helpful. And, other than the stated "design flaw", the jeans are sturdy.
