The Men’s Merino 250 BASE LAYER Pattern Crew from Smartwool is the only base layer you’ll need to combat the cold. Merino 250 is heavier than standard merino while remaining super soft. It provides optimum breathability, moisture-wicking, and warmth for ultimate comfort in every climate. The interlock knit adds durability while the shoulder panels and flatlock seam construction are designed to avoid chafing by moving seams away from areas with more contact for increased softness. The slim fit allows plenty of room for movement while minimizing bulk for a slender silhouette.
