Warm
Color: Mock-black Size: Large
Very warm,seam to be good quality and have some weight to them,they have two seams on each side of the but ,doesn't bother comfort. Great for layering on a cold day . I am 5 foot 10 180 pound and little belly, large fit good, when washing wash alone in cold water dry on low heat is a must. If you order xl make sure you read the size chart, I ordered xl an way to big had to exchange for large. Over all Very nice warm , I would recommend these just check the sizes, . The black one's have a quarter neck keep your lower neck nice and warm. ... ... show more

10 out of 10 or 5 stars
Color: Mock-black Size: Medium
Never put thermal underwear in a clothes dryer because high heat and tumbling break down elastic fibers, shrink wool, and ruin moisture-wicking performance
