What Our Gearhead(R) Experts Are Saying:"I've put these through track workouts and longer road sessions. The deep side splits open up airflow in a way that makes a real difference when pace and temperature both climb. These are the shorts I reach for when the workout actually matters."The details that make a running short great are almost always the ones you stop noticing - a liner that never shifts, a hem that never catches, a waistband that disappears at mile one and stays that way. The District Vision Layered Training Shorts are engineered around exactly that kind of invisibility. The 3-inch split hem is where the design commits to performance. Deep side splits open up airflow along the inner leg and increase range of motion at the moment of maximum extension, reducing the drag that longer or less considered hems create.
