These 2 pants are made to a functional, comfortable pattern and pack light and small. For ventilation and convenience, #5 YKK two-way zippers run down the outside so the pant legs fit over boots.

They provide a remarkable amount of extra warmth. Machine wash. S (28-30), M (32-34), L (36-38), XL (40-42), XXL (44-46).
