Whether hiking, in the gym, or in the icy winter: CALIDA thermal underwear for men keeps you comfortable both under high physical strain and in sub-zero temperatures. Our product lines are perfectly tailored to the diverse needs of active men with a strong sense of fashion and style.
Are you looking for comfortable functional underwear for men that won't let you down even at very high or low temperatures and during strenuous activities? At the same time, do you have high standards for the appearance of your underwear? Then our men's functional underwear is exactly the right choice for you; for every occasion!
While selected materials ensure unique temperature regulation, you can discover various cuts and diverse designs in our product lines; from boxer shorts and briefs with elastic soft waistband to seamless functional underpants for men and body-hugging functional shirts and undershirts with round neck or V-neck; at CALIDA, modern men find functional thermal underwear in trendy looks and classic colors like black, white, gray, and red.
The special features of our men's functional underwear are not only evident in the various fits but also in the unique workmanship of the materials; because the choice of fabrics makes thermal and functional underwear truly functional. Discover long underwear and long-sleeve shirts from our WOOL & SILK product series, made from a noble wool-silk blend, that keeps you warm in low temperatures without making you sweat.
In our CLEAN LINE, be convinced by the breathable TENCEL™, which barely noticeably hugs the skin, making short-sleeved shirts and underwear perfect companions throughout the year. The patented QUICK DRY EFFECT SILVERPLUS ensures a quick absorption of moisture to provide optimal comfort even during significant exertion.
Equally comfortable and gentle, and also odor-inhibiting, is the TENCEL™-cotton mix from CALIDA's popular FOCUS product series. Convince yourself of the special properties and choose between cooling, warming, and temperature-regulating materials in the highest CALIDA quality!
