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 ~ Doesnt add weight or bulk and never washes or wears out
Partial stretch fabrication promotes unrestricted mobility and second-skin fit
Strategically placed flatlock seams for nonchafing comfort
