Mermaid Tails for Girls, Kids, and Adults with Monofin

Sun Tails' swimmable mermaid tails allow you to become a magical mermaid, powered by an unbeatable mermaid monofin. Our premium, fade-proof fabrics are custom-designed with vibrant, realistic scale patterns, ensuring a soft, safe, and authentic mermaid experience.

To complete your mermaid metamorphosis, our matching mermaid scale swimsuits are made from the same high-quality swimsuit material as the tails. The top features a neck strap and back strap for excellent support and a custom fit, while the hipster-style bottoms provide comfort and a sleek, tugless look. Available in toddler, child, teen, and adult sizes.

The Sun Tail mermaid monofin has been engineered to propel you efficiently through the water using the dolphin kick. An adjustable Velcro strap secures your feet for comfort, stability, and control, making fancy mermaid turns and flips much easier to perform. The foot pocket separates your feet to prevent ankle rubbing, and the soft fabric cushions your feet. Our specially designed fin is incredibly strong and durable.

Our mermaid tails are stretchy and forgiving in their sizing. Child tail sizes (M, L, XL) come with the keiki (child) monofin, while the teen/adult sizes (JS, JM, JL) include the nunui (teen/adult) monofin. Both monofin options are made to fit a wide range of foot sizes, with the keiki fitting US child size 10 to women's 7, and the nunui fitting women's 6 to 12.

Care instructions are simple: After swimming, rinse in cold water and lay flat to dry. The tails and monofins are also machine washable, simply wash in cold water and tumble dry on low.

Backed by a 1-year warranty, our mermaid tails and monofins are virtually indestructible, with a mer-shield coating that protects against wear and holes while you swim. Enjoy hours of fun in the pool, lake, or ocean, swimming with grace and speed like a real mermaid.

In addition to our standard mermaid tails, we offer a variety of other mermaid-themed products, including toddler mermaid tails, mermaid bikini swimsuits, and adult XL/XXL mermaid tails and monofin sets. Check out our other listings to explore the full range of options.
