This colorful option features realistic scales and tail, and with the attached monofin, you can even swim like a mermaid under the sea. Our Aurora Borealis mermaid sets allow you to get a discount by ordering your mermaid tail and fin together. Just pick the size tail you want and we will provide the right size fin. New Mer-Shield Coating protects mermaid tails from wear and holes. Superior design, comfort, and control have earned our monofins two patents. Child sizes M - XL will come with a Keiki sized fin.
