Fin Fun Mermaidens - Mermaid Tails for Women, Teens and Adults with Monofin

Vibrant and realistic designs transform you into a Mermaid at the pool or at home with our Mermaiden line, showcasing 9 beautiful fade-resistant colors. The Premium Swimsuit Material features a Tail Skin that is resistant to the effects of sun, pool chemicals, and wear, with 4-way stretch for fit and comfort (size down if between).

Backed by a 1-Year Tail Tip Warranty on Reinforced Tips, our Mermaid Tails are designed to last 20x longer. The Patented Monofin included gives your mermaid tail shape and propels you through the water in a natural mermaid motion. Comfortable and strap-free, the Monofin allows for easy foot removal using the Quick-Release Method, while meeting US and European safety standards.

Safety is our #1 priority, as we strive to inspire others to live their dreams through our innovative and imaginative products. Integrity, Excellence, Innovation, Charitable Giving, and Customer Service are the core values that drive our brand.

Fin Fun was founded in 2009 when a grandmother fulfilled her granddaughter's wish for a mermaid tail. Since then, we have provided quality mermaid tails to Mers around the world, while donating generously to children's causes. Today, Fin Fun continues to be owned and operated by many members of the Browning family, with Grandma Karen and her husband Jerry still actively involved.

Our Mermaid Tails come in a variety of collections, including Mermaiden, Fantasy, Limited Edition, and Atlantis. We also offer Matching Mermaidens Swimwear, Shark Fins & Monofins, and Wearable Animal Blankets.

The Quick-Release Method allows for easy and safe removal of the Monofin in or out of the water. Simply push away from the Monofin with one foot, use your free foot to push the Monofin away completely, and then pull the tail below your hips to swim out.

We recommend children wait until they are at least 6 years old and a strong swimmer to swim in one of our mermaid tails, with adult supervision being a must. Our tails are designed to be open at the bottom to make it easy to put on and remove the Monofin, keeping your mermaid safe while swimming.

Check out the size guide to ensure you select the perfect fit. All Mermaid Tails sold on our platform are proudly designed in Idaho, USA. Our Elite and custom tail lines are made by us in Idaho Falls, while our other lines are produced by a network of international manufacturers who must meet our strict quality standards.
