PRODUCT QUICK HIT: The North Face Isotherm Jacket

When winter hits, we have to get serious about our running wardrobe. One piece we really love is the Isotherm Jacket by The North Face. This soft shell allows you to get out in even the coldest of weather (make sure you layer properly underneath!) thanks to wind and water resistance coupled with reflectivity and a great fit.




  • Stretch panels under the arms and on sides of core. These panels are crafted with FlashDry™ fabrics, which are engineered to accelerate the removal of moisture from the skin and speed up evaporative drying.  FlashDry™ enables you to stay drier, more comfortable and out performing longer in a wide range of weather conditions and environments.
  • Body constructed from WINDSTOPPER® fabric, which utilizes an ultralight inner membrane technology that combines total windproofness with maximum breathability.
  • 360-degree reflective taping for runner safety in dark or low-visibility conditions
  • Athletic, tailored fit. This piece fits true to size (whatever size you’d take in a running top will generally be your size in the Isotherm).


We’ve paired the Isotherm Jacket with the Winter Warm Tight by The North Face and the Dash Seamless LS by Saucony.

The Isotherm Jacket is available in our Boston, Brookline, Cambridge, Melrose, Norwell, Shrewsbury, and Wellesley stores.
