I bought this set for my daughter and she absolutely adores it. Ever since it arrived she has been obsessed with it and had me carry her to her friend's house to show her friends. She adjusted to swimming with a monofin pretty well. The most difficult part was putting on the monofin and the rainbow tail but it definitely became easier once we got more used to it. We were even sent an extra gift which my daughter loved

Excellent quality

While on the pricey side, you truly get what you pay for. The material is super soft and easily stretched, just as advertised. The monofin goes on easily. If you take care of your tail, it’ll last until your mermaid outgrows it! Well worth the purchase!

Great to work with

I emailed them because a item was missing. They immediately got back to me. Within a couple days it was delivered.

Best Mermaid on the Market

Amazing!! I have purchased mermaid tails from several companies and this mermaid tail is both the best quality and price. My daughter loves it!! The fabric tail is similar to Fin Fun and is a swimsuit type fabric. Our Fin Fun tail has faded over time but this tail still looks like new after many uses. The biggest difference is the monofin. The Sun Tail monofin is amazing. It provides much more propulsion and control than Fin Fun and is so much more comfortable than the Finis monofin. The Finis fin gave my daughter blisters. This tail is by far the best mermaid tail for swimming we have used. I wasn't sure about buying another mermaid tail but I am very happy I did!!!
