What a sunny little number. Our “Happy as a clam” knitted crew is made from a blend of sustainable cotton and SeaCell™ (which is derived from seaweed and wood pulp). It’s produced using an eco-friendly process from sustainable raw materials using methods that save both energy and resources, making it completely biodegradable. Cool, eh? So now you can wear this incredibly cute knit safe in the knowledge that you’ve made the world a slightly better place.
