Bought these as riding jeans, spent a fortune, and they are awesome when I wore them. But I typically only ride in the summers when it is too hot to wear these. So I've only worn these a handful of times.
Also I've lost a lot of weight so the 34 waist is too large. (I'm 5'10" now 163-170)
These come with the armor in the hips and knees.  
I believe these are the "Heritage" (75% coverage of Pekev lining), and the color is a dark blue wash, indigo, with that vintage brown stitching. They do have some stretch. They retail for $270. Yikes.
