THESE ARE OUR WARMEST WOOL THERMALS. Merino wool has quickly become the choice of all avid outdoor enthusiasts. Merino wool thermal underwear is super soft and does not itch like traditional wool because merino sheep wool is much finer and thinner making it softer than regular wool. Our expedition weight merino wool thermal underwear is the heaviest weight available and is sure to keep you warm in the coldest weather. All of our Minus 33 brand thermal underwear feature flat lock seams which means that you won't feel the seams against your skin. We typically sell out of this thermal underwear fast through the winter season so don't wait or it will be gone when you need it.
