Mermaid Monofin - Swimming Fin for Kids and Adults

The Mermaid Monofin Swim Flippers, engineered and designed by Sun Tail Mermaid, are built to move the swimmer efficiently through the water using the dolphin kick. Our products are constructed to last, offering the highest quality monofin for swimming. With a 1-year promise and free replacements for rips, tears, and breaks, our monofins are designed to provide unparalleled performance and durability.

The newly redesigned foot pocket of our monofin features thicker neoprene, providing more comfort and durability. The plastic fin is virtually indestructible, and the realistic ridges add beauty while offering superior propulsion through the water. The adjustable Velcro strap securely holds the foot in place, allowing for comfortable, stable, and controlled movement in the water, making performing fancy mermaid turns and flips much easier.

Our monofin separates your feet, preventing your ankles from rubbing together, and the soft fabric cushions your feet, unlike most other fins that rest on plastic. Sun Tail Mermaid monofins come in a rainbow of ten fun colors, allowing you to match your mermaid tail or leggings.

Using our monofin inside our fabric mermaid tails is what makes the tails look realistic, and it propels you through the water like no other mermaid monofin on the market. Our specially engineered fin is super strong and designed not to break, and we offer a 1-year promise, which means we'll replace your monofin at no cost if you experience any rips, tears, cracks, or breaks.

The Sun Tail Monofin is available in Keiki (child) size for ages 6 up to a women's size 7 shoe, and the Nunui (teen/adult) size that fits folks up to a men's size 13. In addition to the monofin, we offer Mermaid Tail Skins (in child and adult sizes), Mermaid Tail and Monofin Sets, and Matching Mermaid Bikini Sets, as well as Mermaid Tails for Toddlers.

Our superior quality, function, and design have earned our monofins two patents (US Patents 9561401 and 9925416), and they are proudly made in the USA. Designed for swimming with great propulsion, control, comfort, and safety, the Sun Tail Mermaid monofin is the ultimate choice for the modern mermaid.
