Dressing comfortably starts with selecting the right men’s underwear. Every man knows whether he prefers boxers or briefs, whether he buys cotton blends, flannel or silk. But besides standard men’s underwear (boxers and briefs), winter activities require the warmth of long underwear. Since this thermal layer is the closest thing to your skin, most men’s long underwear is made of breathable, moisture-wicking fabric. Unlike traditional cotton long underwear, performance fabrics aid in the evaporation of sweat and prevent rapid cool down. It’s important to consider weight when choosing men’s long underwear: lightweight, midweight or expedition weight. Look for long underwear or wicking T-shirts featuring technological innovations like X-Static® for increased odor-resistance or Dryflo® for enhanced wicking. Merino wool and featherweight silk men’s long underwear are natural options for wicking long underwear.
