The Kari Traa Malia Half-Zip is a slim fit, high-collared zip neck baselayer made of a merino wool/Tencel blend. One of the warmest, fastest drying, and most comfortable baselayers in the Kari Traa family, the Malia has a jacquard knit front and contrasting panels on the back, side, and arms that strategically wick moisture. Derived from the bark of eucalyptus trees, Tencel is renewable and sustainably harvested.
