Do you like exercising, hiking, or playing outdoors in the cooler months? How about working in the yard or going for walks? Do you do fieldwork, fish, or hunt? Or maybe you enjoy engaging in outdoor sports or playing in the snow? Chances are good there’s some outdoor activity you do in the winter months. And if so, you’ll probably find a set of comfortable, functional base layers—lightweight pieces of clothing to wear under sweaters or jackets or pants—to be a worthwhile investment.
