These NWOT Anti-Slip Yoga Pants have a rubberized anti-slip grip on the foot that allows you to practice yoga without a mat. Quality thickness of the material in the pants, but not "scuba-gear-like." Electric Yoga's moisture wicking material is called DRYFLEX that absorbs sweat (88% Micropoly, 12% Spandex). The foot grip separates the big toe from the rest of the toes, like a flip flop. There is no size sticker in the pants. When placed on the mannequin, we deemed them a size small.
