I really like Champion's yoga style pants - I have several pairs.  These are similar to many that I own in construction.  I like the material and the fit, but the legs are very short for me.  I am only 5'7" - so not overly tall, but the legs barely hit my ankle, even wearing the pants below my waist.  This might work for you, if you run, or spin, and don't want your pant legs too close to the ground, but my preference is a longer leg- breaking just above the floor.
