With these lounge pants from the CIRCULAR line, CALIDA makes a clear statement by combining sustainability with modern design. The product is 100% circulable and once the wearer is finished with it, they can return it to CALIDA. The natural raw material for the TENCEL™ finish is wood, which is processed in a resource-efficient closed-loop cycle. TENCEL™ is exceptionally breathable, extraordinarily soft and gentle on the skin.
