Boys thermal underwear Kilpi NATHAN-JB dark blue

The Kilpi NATHAN-JB long-sleeved thermal T-shirt for boys is made of quick-drying OPTI-DRY material, which is pleasant to the touch, extremely elastic, wicks moisture away from the skin well and thus maintains thermal comfort. The shirt has a round neckline. A seamless knit with flat seams and a body-hugging fit maximize comfort when moving and wearing. NATHAN-JB is available in several sizes for the smallest and older boys. We recommend also purchasing Kilpi NIEL-JB underpants as an ideal set not only for skiing, hiking or other outdoor activities. Material composition: 53% polyamide, 41% polyester, 6% elastane
