Mermaid Monofins by Mertailor

Find the Monofin That Gets You Swimming.

Every mermaid swims a little differently. Maybe you want something compact, simple, and easy to start with. Maybe you are ready for the flexible feel of a silicone Fantasea Fin. Either way, your mermaid tail starts with the fin underneath it.

Start simple. Go silicone. Get bigger. Make it yours.
