The hair on your neck stands up, your breath visible as sunlight reaches through cold air. Maybe an extra layer, just to be sure? Our Longsleeve Winter baselayer is a utility piece for days with in-between weather. The flexible fit knit perfectly compliments our Everyday Longsleeve jersey for a middle layer of temperature regulation on cold days. The merino wool fabric is soft to the touch and benefits from natural odor resistance and moisture-wicking properties.
