The Kilpi NATHAN-M men's thermal long-sleeve shirt in black is designed to offer maximum comfort during winter activities.

Made from OPTI-DRY material, the shirt instantly wicks moisture away from the skin, maintaining thermal comfort throughout the day.

The seamless knitting with flat seams offers softness and reduces irritation, while the close fit follows the body's curves for maximum freedom of movement.

With a round neckline and modern design, the NATHAN-M is an ideal choice for skiing, hiking, or other outdoor activities.
