The Zeroweight Warm Running Tights 2.0 are now made entirely from recycled materials – featuring a waterproof and windproof softshell fabric on the thighs and a warm, ultra-stretchy material on the lower legs and back – making them the ideal choice for running at pace on cold days. Functionality is not overlooked either: the pre-shaped knees and adjustable bonded waistband are complemented by reflective details and multiple pockets. With these warm and weatherproof running tights, you'll be ready to head out even when you don't really feel like it.
