Classic Thermal Base Layer, Pool Blue Joviansphere

A Smartwool classic, this wintertime go-to top is crafted in a soft, itch-free merino wool, which naturally helps regulate body temperature and transports sweat away. It has long sleeves, a crew neckline and a flatlock seam construction that helps prevent chafing. The fit is deliberately close; we recommend sizing up if you want a roomier fit.
