Yes, you know Smartwool socks, but do you know Smartwool's base layers? The Evie Lou crew is obsessed with them for layering in colder weather. We wear them for outdoor activities from running to biking to skiing, but they are also ideal for our freeze babies, who abound here in Cleveland's winters! This hoodie is crafted in a soft, itch-free Merino wool, which naturally helps regulate body temperature, transports sweat away and cancels out odors. It has long raglan sleeves and a flatlock seam construction that helps prevent chafing. A kangaroo pocket sits on the waist. The fit is deliberately close; we recommend sizing up if you want a roomier fit.
