Longjohn 3/4 length 160 gr/m2 100% Merino to wear closest to your skin, with extra patchwork for protection on knees and bum. Solid waistband and 3/4 length legs for optimal fit together with ski & snowboard boots. Keeps your body temperature in a comfortable zone, no smelling or itching. When it's cold it keeps you warm and when your activity intensity goes up it breathes well and keeps you cool. Since merino is so smart you don't have to wash it after each use, which makes it the smartest environmental thing to wear.
