Besides that, I'm well pleased with the pants; perhaps I'd add some welt pockets in the back in another version. There's an invisible zip on the left side and the pockets are great because they are large and roomy without appearing bulky. Perfect for hand storage.
I can't remember where I got the fabric; all the black fabrics in stash tend to meld together in my mind.
The pattern is Burda 2-2010-102.
