The product description says these are 98% cotton, but they're not.  At least not the ones I received -- they're only 74% cotton with 25% polyester and 1% spandex.  All that polyester has its pros and cons.  On one hand, the jeans don't stretch out as much as most when you wear them.  The downside is that they aren't as soft as most jeans, they don't breathe enough wear comfortably in warmish weather, and for some reason, dirt shows up on them more and doesn't rub off with a damp cloth.  I have a toddler and a baby, so I often have grimy hands on my clothes and in these jeans I really look a mess by the end of the day.
Nonetheless, I appreciate the high waist that holds in my now-mushy mommy belly, they fit me well and are flattering.  I like these jeans better than American Apparel's Easy Jean or Levi's Perfectly Slimming jeans.  Still searching for the perfect high-waist jean, though.  Open to suggestions...
