The North Face Isotherm 1/2 Zip

Retailers' Descriptions

Here's what other sites are saying:

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.


This innovative hybrid top is constructed with a wind-resistant core and polyester blend. FlashDry protects your core, provides warmth and helps regulate your temperature on your cold-weather runs.


Regulate your body temperature in cool conditions with a lightweight hybrid running top that features a wind-resistant woven front that's flanked by stretch-knit panels with wicking FlashDry fibers for exceptional moisture management.
