The Armor Lux Callac Tee, also known as the Heritage Tee, is a core style at Frontiers built around durability, comfort and a clean, everyday shape. Made from a compact cotton jersey using twisted yarn construction, it offers a denser, more stable knit that holds its shape over time. Finished with a thick ribbed crew neck and a straight hem, it works equally well worn on its own or layered. These always sell-out so be quick!
