The North Face Warm Zip-Neck base layer provides maximum thermal protection and moisture management for low- to medium-intensity activities in cold weather. FlashDry technology dramatically improves dry time and breathability.

• Polyester and polyolefin two-layer double-knit fabric with FlashDry fiber
• FlashDry Warm:
  ~ Polyolefin inner layer traps heat for high warmth-to-weight ratio
  ~ Microporous FlashDry particles in fiber pull moisture to outer layer and prevent fabric from sticking to skin
  ~ Ultramicrofilament polyester outer layer spreads moisture for accelerated evaporation and drying performance
  ~ Ventilation pores allow water vapor to escape
  ~ Improved odor control
  ~ Doesn’t add weight or bulk and never washes or wears out
