The Craft Active Extreme Zero Windstopper Crew Neck Long Sleeve base layer features a Gore Windstopper front panel that really helps to keep the core warm in cold and blustery conditions. It is almost like having a secret bullet proof vest against the wind. Craft is one of the few companies that licenses the Gore Windsopper material known for its ability to seal out the wind but effectively expel moisture so you get incredible wind protection without moisture buildup.
Craft's Zero fabric is designed to perform in a wide -10 to 50º F temperature range. The medium weight Zero fabric is optimized for temperature control and moisture transfer with filament yarns and air-channeled polyester construction. One of the best features of Craft base layers is they are engineered to work perfectly especially during moderate to high intensity racing and training.
