This Hot Chillys kids' thermal shirt is a long time favorite with a cotton-like hand feel that does not hold moisture. Made with theMoisture Transfer Fibers it moves moisture away from the skin to be evaporated so you stay warm and dry. Spun polyester yarns give this long sleeve base layer a soft hand feel and spandex gives it a 4-way stretch so the body fit shape will move easily with you. This kids' thermal shirt is perfect for performance sports or casual use.
