I have been looking for a decent workout pant for a while. These are it. The rise is perfect, just the right amount of compression. No rough spots and breathe fairly well. AND, I am a tough fit at 5'10" and size 4. Just bought 2 more pairs.
I also bought the xlarge...thinking the large might be too snug. I was wrong. These need to be snug. The compression feels great. I use them for Yoga - they are awesome!!
I thought these were good capris at a fair price but would've liked a zipper pocket on the back of the waistband. That was until I figured out that my iphone 4s can comfortably fit into the hidden waistband pocket when I run. Now I own three pairs in different lengths. They're perfect. For size reference I'm 5'9" 138lbs and go with the small. Hits below the knee but I don't notice them riding up enough to bother me - with the small size everything, including phone, stays put.
