The Women’s Merino 250 BASE LAYER Pattern Bottom from Smartwool provides the comfort you need for all seasons. Merino 250 is super soft and heavier than standard merino, while still providing optimum breathability, moisture-wicking, and warmth for ultimate comfort in every climate. The interlock knit provides durability while the merrow seam construction is designed to avoid chafing by moving seams away from areas with more contact to increase softness. The functional fit is designed to improve movement while maintaining a slim silhouette for an enhanced aesthetic.
