I received and returned this product today. I tried them on and they were comfy on my legs - in fact, nice and heavy like jeans, but stretchy and soft like sweat pants, BUT 1. there were a couple defects in the sewing (and the hem & on the butt) and 2. they fit funky on me (5'4") where the drawstring came up to/above my waist... it was weird. I suppose if I had a longer mid-section it wouldn't be so bad, but I haven't worn anything that high up on my waist since the 80's. It's hips or below for me.  With a shirt over the waist, they were cute with back pockets sewn in and front pockets - even the little one in front - all functional. The length of the legs would probably be OK for those that are 5'2" or 3" to maybe 5'5" or 6" (at most). Again, depending on your body type, but I liked the length for me - just slightly longer than me. I'm a little heavy right now (150 lbs), too, so I got the medium & and they still felt a little big - although not falling off of me.
So, I can't speak for washing and wearing them and actually getting use out of them, but if they didn't have the defects and didn't come up so high on my waist, I'd probably be wearing them right now. They're just not as I had expected.
Good luck!
