Made from a blend of wool and polyester, the Stoic Merino Blend Crew Baselayer Top strikes the perfect balance between comfort and performance. Merino wool adds soft warmth that keeps the fabric smelling fresh after long mountain days, while polyester increases the durability of the fabric, and enhances its ability to wick moisture away from your skin. The form-fitting cut can be layered beneath your favorite puffy and shell, while the classic crew cut is easy to wear.
