Designed for cold weather conditions, the thermal base layer uses the latest in heat retention technology to offer an innovative fabric that keeps heat closer to the body while at the same time wicking moisture away. The result is increased warmth while your body remains dry. It’s the ideal base layer when the temperature drops. Our thermal base layers can also be customized. We do not print the entire base layer, just the area below the neck. Check out the picture — where our Champion System logo appears is the area where we can print your logo.
