Merino wool blend thermals for men have been a favorite each winter season. The 100% cotton inside is super soft next to your skin. It pulls the sweat away from your skin and traps your body's natural heat right where you need it. The merino wool content pulls the moisture away from the inner layer allowing it to evaporate leaving your skin warm and dry. These are designed for low to medium activity in very cold to extreme cold temperatures. These versatile mens thermals can be worn to the office or to the football game and even hunting.
