Wear this 6.3 ounce mid-weight two-layer thermal for exceptional warmth during very cold weather. This long sleeve crew features a cotton inner layer for next-to-skin softness, the natural insulating performance of merino wool, and a tagless design with flatlock seams to help avoid irritation. Duofold began its tradition of innovation with the introduction of the first two-layer thermals, Duofold Originals. Designed for a wide range of outdoor activities, its two-layer construction combines the next-to-skin softness of cotton with wool in the outer layer, providing great thermal insulation. As these styles have been used for low intensity activities, our commitment to delivering comfort and quality has remained constant.
