I haven't worn these capris, so I can't comment much on performance. They are size medium, in black. I'm 5'8" and 135 pounds and these fit well, but it doesn't feel like you're wearing all that much when you have them on - they are seamless, to be high-tec running capris. They have reflective marks on the legs, a drawcord waist. The fabric also collects dust and fuzz very easily (not that it matters when you're out running.) Here are the details from The North Face's website:
