Our moss green T-shirt is manufactured with attention to detail, from 60% cotton and 40% polyester, which are both soft, comfortable, and durable materials, perfect to wear for extended periods of time. The crew neck offers lightness and ease of wearing in outdoor activities. The T-shirt is designed with love for the rich Irish history, inspired by the ancient manuscript of the Book of Kells, one of Ireland's finest national treasures. The intertwining swirls and knots represent the Celts' belief in the connectivity of all things in the universe, a symbol of eternity.
