Thermal Merino Rib Inset Top, Chalk Violet HeatherThis new style from Smartwool looks as good as it'll make you feel on chilly days! It combines the brand's signature thermal merino wool with a new merino waffled rib knit. It has a drop shoulder construction, with a relaxed funnel neckline and a deliberately boxy silhouette. The fit is rather relaxed; if you are used to sizing up in Smartwool's base layers, we suspect your regular clothing size will be just fine in this style.
