I've been purchasing Matix Gripper denim for quite a while.
Many people don't realize it, but whether or not they are 100% cotton / 98% cotton, 2% spandex or 2% lycra is all dependent on the colorway. Be sure to do research on your color choice before purchase i.e. check other sites for more exact details
Also, from 2006-2008 all of the inseams for size 30 was 32". Now in 2009 they have changed the inseam to 30" for size 30.
