Warm is an understatement. Smartwool's Women's Intraknit Thermal Max Merino Base Layer Bottom uses 100% ZQ-certified Merino wool to help keep you comfortable on every cold-weather outing. Insulating terry loops are seamlessly paired with mesh ventilation to balance warmth and breathability, while knit-in reflective elements enhance visibility in low-light conditions.
