The Malia Long Sleeve is a slim fit, round neck base layer made with a Merino wool/Tencel blend. One of our warmest, fastest drying, and most comfortable base layers, the Malia sports a jacquard knit front and contrasting panels on the back, side, and arms to strategically wick moisture. Derived from the bark of eucalyptus trees, Tencel is renewable and sustainably harvested.
