The Viking Altis Man SET men's thermal underwear combines merino wool with elastic technical fibres in a seamless set made for cold days. Merino provides natural thermoregulation, so it keeps you warm in the cold without overheating when you move. The 250 gsm fabric makes it an ideal first layer under a ski jacket, softshell or winter hiking gear.
The seamless construction reduces the number of seams and with it the risk of chafing during long wear. The elastic knit hugs the body and does not restrict movement, so the set sits well under further layers. The antibacterial treatment helps limit unpleasant odours, which makes Altis a good choice for multi-day hikes and all-day skiing.
The set belongs to the Extra Warm group and is designed for the coldest days of the year. If you are looking for a slightly lighter alternative, take a look at the Viking Eiger SET in the Warm level. You can find more models in the Viking range and in the thermal underwear category.
