This pant features the same horizontal fly and supportive “kangaroo pouch” front that has made Munsingwear briefs a favorite for many years. The traditional waffle knit traps the air and acts as an insulator to keep you warm. Made of 60% cotton and 40% polyester for low shrinkage. Extra long cotton/spandex cuffs allow no cold in and can be folded to the perfect length. Inside brushed elastic waist for comfort. Machine wash and dry.
