The North Face crafted its Flight Series Women's Isotherm 1/2-Zip Shirt to keep you running in anything from brisk fall mornings to snowy winter days. It features wind-resistant fabric and FlashDry panels on the collar, sleeves, and back to improve moisture management and temperature regulation. Merino wool blend underarms also regulate your body temperature to keep you at an ideal temp whether you're running your hardest or just warming up in cold weather. Its slim fit keeps all of this soft fabric close to your body, and a dropped hem makes sure your lower back doesn't feel a cold draft. The two-way 1/2-zipper at the front lets you control how much ventilation. Pull out the inner mitts with thumbholes to keep your fingers nice and toasty, or tuck them away when you don't need them. Store your key and wallet in the zippered chest pocket and get running regardless of the conditions.


Prepare for your cross-country ski workouts in The North Face Isotherm women's half-zip top. It uses a warm blend of merino wool and FlashDryTM fibers and a zip to help regulate your temperature.


Dial in your protection when running long distances in cold conditions with a hybrid top designed to regulate your temperature. The body mapped construction protects your core and shoulders from the wind and cold without sacrificing breathability and mobility. The wind-resistant front is flanked by stretch wool panels with wicking FlashDry fibers around the sides, down the center back and under the arms for exceptional moisture management. When your hands need light protection in chilly weather, pull the mitts out from the internal cuffs and over your fingers. The half-zip neck provides extra coverage when fully zipped, or quick ventilation when unzipped.
