Introducing the Cotton Thermal King Russell Honeycomb Hem Round Crew Neck Long Sleeve Pullover from Healthknit. This long-sleeve pullover uses a 3D honeycomb thermal structure developed by the U.S. military for activities in sub-zero Arctic temperatures. The three-dimensional knit traps body heat and its high absorbency keeps you comfortable even in mild weather or indoors. While excellent as an undershirt, it's finished with specially ordered yarn for durability, allowing it to be worn as a top. The rounded hemline creates a feminine silhouette. It is new, but please understand that it is a personal item. Those who can understand this are welcome.
