A midweight base layer bottom for long, cold days on the hill or the trail. Helly Hansen pairs a LIFA fiber layer against the skin, which moves sweat away fast, with a Merino wool outer layer that holds warmth even when you're working hard. The result stays comfortable through a sweaty bootpack at Meadows and the chairlift ride that follows. The fit is close without being restrictive, so it sits cleanly under ski pants or a shell.
