Fin Fun Mermaid Tail Types: Finding the Best Tail for You


Fin Fun mermaid tails are for merfolks of all ages, interests, and backgrounds! Let’s go back to the basics and go over our unique lines of tails, plus custom mermaid tails too. Each line has something unique to offer, so you’re “shore” to find the best mermaid tail for you!

Sparkle costume mermaid tails are reminiscent of Fin Fun’s very first fabric tails. They come in three bright, solid colors with glittering foil woven into the fabric so they shimmer and shine in the sun. 

These are the perfect costume mermaid tails for kids, though they also come in select adult sizes. We recommend wearing them for play and in the bath away from harsh chlorine and salt water that can damage the shimmering fibers. 

To sum up, Sparkle mermaid tails:

  • Are great costume tails
  • Consist of lightweight, breathable, 4-way stretch fabric
  • Have an open fluke for easy monofin insertion and water flow
  • Meet international safety standards

The Mermaidens tail designs came after Fin Fun’s Sparkle tails. They feature detailed scale designs without glittering foil in the fabric. They come in nine beautiful colors that span the rainbow — one of which is a rainbow mermaid tail. 

Each design is based on a member of mermaid royalty with a special ability (called a Mermaiden), which is a great start for those trying to find their mersona. We recommend these swimmable mermaid tails for beginner mermaids and experienced hobbyists alike!

Mermaidens tails have:

  • Bright and colorful designs
  • Lightweight, breathable, 4-way stretch fabric
  • Machine washable fabric
  • An open fluke for easy monofin insertion and water flow
  • Reinforced Tail Tips backed by our 1-Year Tail Tip Warranty
  • Met international safety standards

Fin Fun is proud of their advancements in construction and design over the years, and our Elite mermaid tail line pushed us to try something we’d never done before. These tails are engineered for professional merfolks with durable scuba knit fabric and large, flowing flukes. While all of our other tails use our Original Patented Monofin or Advanced Monofin, we created the Elite Monofin to fit the size and power of the Elite tail.

They also feature our most realistic designs to date with finely detailed scales and flowing hip fins in vibrant hues. These tails are perfect for creating memorable experiences for children and those seeking more magic in their lives.

Here are the other features included in our Elite mermaid tail line:

  • Recommended for professionals and advanced merfolks
  • Soft, breathable scuba knit fabric with a vibrant design
  • Wide, flat waistband for comfort
