We did a search of the top selling mermaid tails on Amazon to see who has the best rating. Here are the rankings (based on their Amazon reviews) at the time of the writing of this post:
#1 Sun Tail Mermaid
4.7 stars out of 5 (755 reviews)
When looking for a mermaid tail for swimming, the key is the monofin. This is where the Sun Tail Mermaid set shines. Their monofins are superior to the monofins included with other mermaid tail sets on Amazon. The Suntails mermaid tail gives you the best control to do tricks, flips, and turns in the water. They also provide the best propulsion and speed. We did several speed tests and Sun Tail Mermaid was the clear winner in each of these tests. The Suntails monofin and mermaid tail set costs $69.95 for child sizes and $79.95 for teen/adult sizes. These swimmable mermaid tails also include a 1-year warranty with free replacements for rips, tears, or breaks.
#2 Fin Fun
4.7 stars out of 5 (2,711 reviews)
Fin Fun and Sun Tail Mermaid sets have the same star rating so both are good options, but Sun Tail Mermaid provide a better warranty and a better monofin for the same price or $5 less depending on the size. The Fin Fun mermaid tail and monofin set ranges in price from $69.95 for the smallest sizes to $84.95 for the larger sizes. Fin Fun also has limited editions mermaid tails that range in price from $89.95 to $129.95.
4.3 stars out of 5 (116 reviews)
The Shimmertail get fairly good reviews because of its low price. This mermaid tail costs $23.23 but doesn’t have a functional monofin for swimming. It does includes a fin but it is basically just a thin piece of plastic that hold the shape of the mermaid fluke but actually makes it harder to swim. Since the monofin is not functional, the Shimmertail would be similar to buying just the fabric mermaid tail skin from Sun Tail Mermaid or Fin Fun. For just the fabric mermaid tail, Sun Tails charges $29.95 to $34.95 depending on the size and Fin Fun charges $34.95 to $44.95 depending on the size. If you are okay splashing around in the shallow end of the pool and don’t want a mermaid tail for swimming, the Shimmertail is an inexpensive option to accomplish this.
#4 Play Tailor
4.3 stars out of 5 (426 reviews)
This mermaid tail doesn’t include a monofin. It is just the fabric mermaid tail. There are many negative reviews about the quality of the material. It is currently being sold for $17.99.
#5 Lovely Mermaid
4.3 stars out of 5 (1,698 reviews)
No monofin included. This fabric only mermaid tail sells for $27.99. The reviews are summarized by this comment by a purchaser, “Overpriced for the quality. The fabric is cheap and thin.”
4.2 stars out of 5 (1,753 reviews)
This mermaid tail also does not include a monofin and is just the fabric mermaid tail. This mermaid tail only receives a 3.0 out of 5 stars on durability which pulls its overall rating to 4.2 stars. This mermaid tail sales for $24.99 on Amazon.
There are dozens of mermaid tails for sale on Amazon, but if you are looking for a mermaid tail and monofin set to use for swimming, there are only two good options: Sun Tail Mermaid and Fin Fun. The Sun Tail Mermaid sets are $69.95 to $79.95 depending on the size and the Fin Fun sets are $69.95 to $84.95 depending on the size.
If you are looking for just a fabric mermaid tail with no monofin, there are many options ranging in price from $18 to $25. However, many reviewers were disappointed in the quality of these tails. If you are interested in buying just a fabric tail, the high quality Sun Tail Mermaid tail skin without a monofin for $29.95 is probably a better value than the lower quality tails that are $18 to $25.
