The Jersey  long-sleeved jacket Kilpi NATHAN-M  for men  is made of OPTI-DRY, a quick-drying material, pleasant to the touch, extremely elastic that  wicks moisture away from the skin and thus maintains thermal comfort. The shirt has a round neckline. The bust part  it is seamless while the sleeves are sewn with flat seams to not irritate the skin. The fitted cut that replicates the curves of the body,   maximizes comfort during movement. We recommend pairing with Kilpi NIEL-M thermal pants as a great set for skiing, hiking or other outdoor activities.
