DESCRIPTIONOur baselayer bottoms are a combination of fine-micron Merino wool and a razor-thin layer of wicking fibers that keep you dry and comfortable. Featuring our DUAL SURFACE(TM) Precision Blended Wool, nothing in the apparel world comes close to this baselayer in terms of warmth, breathability, versatility, durability, and overall comfort. Athletic Fit. Made in the USA. DUAL SURFACEIdeal for next to skin applications, this fine micron wool construction features a thin inner layer of high performance wicking yarns designed to pull moisture off the body and disperse it on to the outer facing surface of the fabric. Once there, the natural temperature and moisture regulating properties of wool are free to take over, keeping you dry and comfortable long after the furnace stops burning.PRODUCT CAREWhile all of our fabrics are specifically designed for machine care, we recommend protecting your investment through minimally damaging processes. For us, this usually means a cold wash cycle followed by a hang-dry. If you do find yourself in a pinch then it's perfectly ok to throw it in the dryer. In either case, we recommend staying away from those pesky fabric softeners.
