The ODLO Zeroweight Warm Winter Running Pants are designed for demanding runners who want to push their limits day after day. They are made from lightweight, windproof, water-repellent 4-way stretch softshell material on the front of the thighs, while the knee area offers maximum freedom of movement and breathability. An integrated drawstring in the waistband, multiple pockets, and reflective details make these running pants the ideal companion for cold weather.
