Their Merino Long Underwear blends merino wool with the softness and quick-drying properties of tencel fabric. Antimicrobial, moisture wicking, and thermoregulating, merino wool ensures your body stays heated while the temperature drops. The mesh cool zones keep you cool for around the house wear, while the flat lock stitching and no roll waistband make for easy layering. Available in five colors, Mack Weldon believes these will be your most comfortable underwear yet. If it’s not they’ll send you a new style, size, or offer a full refund.
