Cat and Moon Design Bamboo Socks are socks made from bamboo fiber and feature a graphic of a cat and a moon. The design represents the more mystical side of esotericism or can be used as a form of self-expression or as a way to show love for cats or a connection to the symbolism of the moon. The design can also be chosen for its aesthetic appeal. Bamboo socks are known for their comfort and breathability as bamboo fiber is soft and moisture-wicking.
