The Women’s Merino 250 BASE LAYER Crew from Smartwool is a stylish choice for all seasons. Merino 250 is super soft and heavier than the standard, while still providing the wearer with optimum breathability, moisture-wicking, and warmth for ultimate comfort in every climate. The Shoulder panels and flatlock seam construction are designed to avoid chafing by moving seams away from areas with more contact to increase softness. The back body seams are made to wrap around from front to back for a snug fit while giving maximum mobility.
