Its engineered construction helps enhance your performance with a lighter weight and cleaner finish. If you're looking for base layer clothing for cold weather, this one uses Merino Sport yarn that combines the power and benefits of Merino wool with the durability and fast dry times of polyester - creating the ultimate performance-ready top for all of your high-energy activities.
