When you step onto the mat, the world becomes that one room. It's just you, your breath and your movements. These adidas by Stella McCartney yoga tights make sure nothing distracts from that. How? The seamless knit construction, for one — it forms to your body with a second-skin feel and lets you play with your own expression as you flow from pose to pose. Then there's the high-rise waist, which offers full support and coverage from the first sun salutation to the final Savasana.
