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

Made from OPTI-DRY material, known for its quick-drying properties and excellent elasticity, this shirt quickly 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 snug fit follows the body's curves for maximum freedom of movement.

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