Go on, break your own rules today. Push farther, faster there's nothing you can't do in these flexible training tights. Your smart workout partner gives you a leg up with superior functionality like no-chafe seams, sweat-wicking Hydro-Pro material and an elastic waistband with adjustable drawstring on the inside. But feeling good is also about style, which is why this second skin's muted hue is bubbling over with bright little accents. 90% polyester, 10% elastane.
