KLIM'S WARMEST BASE LAYER Sorry! You'll have to replace other base layers in your closet with this shirt - it's just that good. This women's thermal layer is perfect for trapping heat on cold days, but it's moisture-wicking and breathable for sweat management so you won't get the shivers later. Another reason why you'll love it is the cut- an athletic silhouette that fits well on a variety of body types, moves with you, and isn't bulky (ie actually looks flattering).
