The Sun Tail Mermaid monofin has been engineered and designed to move the swimmer efficiently through the water using the dolphin kick. An adjustable Velcro strap over your foot holds your foot securely in place to provide comfort, stability, and control of movement in the water. This makes performing fancy mermaid turns and flips much easier! Our foot pocket separates your feet so your ankles don’t rub together. Soft fabric cushions your feet so they don’t rest on plastic like most other fins. Our specially engineered fin is super strong and won’t break! Our monofin comes in a rainbow of ten fun colors to match your mermaid tails! The fin’s realistic ridges add beauty and give you more propulsion through the water than other fins. You will get the best monofin on the market at an amazingly low price.


Our soft foot pocket is stretchy, comfortable, and self-adjusts to fit a wide range of foot sizes. Our monofin is available in the child size (Keiki) and teen/adult size (Nunui).

The Nunui (teen/adult size) monofin fits shoe size US women’s size 6 to 12. The Nunui is designed to fit people ages 12 to male adult.


You can wear your monofin all by itself or you can also match your monofin to one of our mermaid tail skins for a beautiful look.

Mermaid heaven

Everything from ordering, fixing a shipping mishap, to timely shipping customer service was impeccable. On a tight summer budget we ordered scratch and dent and clearance patterns and every item was perfect. 10/10 recommend!! My girls are thrilled

Great mermaid tail! My daughter can’t wait to use

Bought this on a whim and wasn’t sure what to expect. My daughter immediately loved and can’t wait for summer! High quality! Much better than others we have purchased (different brands)

I purchased a child sized monofin and it was too small. Sun tail mermaid assisted me with important details of fabric, sizing etc. (helpful) once determined an exchange was needed, I was promptly assisted and a few days later I received new size monfin. This company went beyond with their customer service and truly guaranteed their product. It was a great pleasure to do business with them.
