Running in the fall is often glorious, but it also can be tricky. The welcome cooler temperatures make for more pleasant conditions, but you now need to think more about what you're wearing. The New Balance Precision Run 3 in 1 Jacket might better be described as a system for running in colder weather. The wind- and water-resistant shell serves as the top layer in bad weather and moderately cool conditions. The chin-length collar is a nice tough for those cold early-morning runs, allowing you to stay warm at the start but open it up for more ventilation once your body heats up.
