Smartwool Classic Thermal Merino 1/4-zip Base Layer - Women's

The Smartwool Classic Thermal Merino 1/4-Zip Base Layer - Women's is a 100% Merino wool base layer for cold weather pursuits. Ski, hike, run, the fast movement persists even into the winter. The Merino wool fabric regulates body temperature, cooling when it's hot and warming when it's cold, and an updated fit hugs the upper body in all the right spots. A 1/4 zip facilitates on/off and dumps excess heat when physical activity gets more intense.
