What is a Swimmable Mermaid Tail?

A  Swimmable Mermaid Tail, also known as a “Swimtail,” is swimsuit-like fabric combined with a single large flipper, called a monofin, to create a functional mermaid tail.

1.) a Monofin – The plastic and rubber fin that fits on both feet

2.) a Mermaid Tail Skin – A premium swimsuit fabric that wraps over the monofin and swimmer’s legs

Both of these parts are combined and delivered as one piece.

Are Mermaid Tails Safe?

Yes! Mermaid Tails are just as safe as any flipper available. All of our tails can be easily taken off in or out of the water. Of course, adult supervision is required for children. It is recommended that children already know how to swim before using a mermaid tail. This includes being able to swim underwater, while holding their breath. For younger children (ages 5-7) we can produce the tail with an “open tail botttom” for easy monofin removal and walkability.

Do I Need To Buy a Mermaid Tail & a Monofin?

That Depends. If you or your child plans to swim in the water while wearing the mermaid tail, then Yes, a monofin is required. All Swimtails are made to fit Finis Brand Monofins only. If the mermaid tail is for on-land fun only, then monofins are not required, however they do help keep the “tail”shape.

What is the Mermaid Tail Skin Made From?

Our Premium Mermaid Tail Skins are made from a polyester / spandex blend. They are manufactured with a 4-way stretch swimsuit material for maximum flexibility and longevity. The fabric is chlorine safe and meant for water. Our mermatil tail colors and patterns stay brighter, longer. Each tail is made in the USA with care.

Do You Sell Swimsuit Tops?

What Size Monofin & Mermaid Tail Should I Order?

Please see our detailed Size Chart for mermaid tail sizing.

Monofin sizing is as follows: Child size 2-7 / Adult size 5-11

*Please note – swimmers with wider feet within the shoe size 5-7 range should choose the adult monofin for a better fit.
