Are Fin Fun Mermaid Tails Made in America?

All Mermaid Tails sold on are proudly designed in Idaho. Our Elite and custom tail lines are made by us in Idaho Falls. For our other lines, we work with a network of international manufacturers, each of whom must meet our strict quality standards.

How do I know if my child is ready for a mermaid tail and monofin?

We are very passionate about creating the safest products possible. As a general rule, we recommend children wait until they are at least 6 years old AND a strong swimmer to swim in one of our mermaid tails, however adult supervision is a must!

Why are Fin Fun’s tails open at the bottom?

We have designed our mermaid tails to be open at the bottom to make it easy to put on and pull off the monofin inside the mermaid tail. This helps keep your mermaid safe while swimming, as the monofin can be easily removed.

How do I know which size to buy?

49 customers mention30 positive19 negative

Customers are mixed about the fit of the swim fin. Some mention it fits just right and is easy to use, while others say it's a little snug and difficult to put on. The waist is too large, and the tail is very tight. The holes of the fin are very small, and there is no elastic holding the waist up, so it rolls down while the child is swimming.

"...4 year old daughter is 34 lbs and 40 inches tall, and the s/m fit snugly on her legs with room at the waist!..." Read more

"...If pulled up it would go under arms and the waist is loose. Just so tight at the hips, so I assume the small one will be the right fit for swimming...." Read more

Gift for my daughter and she loves it! Material is good quality and the fin part is very durable. It is very expensive, but after comparing all the little girl mermaid fins I found on Amazon, this was the one I felt like would be the most durable for long term use.

Reviewed in the United States on July 22, 2023

My 4 year old daughter is 34 lbs and 40 inches tall, and the s/m fit snugly on her legs with room at the waist! We tucked it into her swim bottoms and it stayed on great in the pool! She LOVED it, it was the hit item of our vacation!

The monofin is easily removable from the opening on the bottom of the fin. It can be rinsed and set out to dry overnight. The cover went through the washer and dryer daily with no shrinkage or issues!

Their feet sit flat on the fin. The “sock” openings were hard for me until I figured that out. Slide the foot in on the fin and then pull the ankle openings over the heel. The ankle openings are a little snug, even for size 9 toddler child.

Overall GORGEOUS, such a great value! So happy, worth every penny!

This was my daughter’s first mermaid tail. With a few practices, she got the hang of it. Super high quality, only a few things. The tail color faded over time, and the monofin got very bent with only a year of use. The tail skin did get stained with some kind of grease. Overall, great tail for first time mermaids!

5.0 out of 5 stars Sizing review for 8yo
Reviewed in the United States on June 4, 2023
Size: Youth Large/X-LargeColor: PinkVerified Purchase
It looked like my 8yo (4’/~60lbs) was right on edge between S/M and L/XL according to some reviews and sizing chart. Ordered the big one to have it last longer, but it is too big length and waist wise. If pulled up it would go under arms and the waist is loose. Just so tight at the hips, so I assume the small one will be the right fit for swimming. If you’re on the edge go with the small one.
Didn’t yet try, but looks like good quality, bright colors, so I just get another small one and keep this for later. Saw quite a few kids with fantasy fins at the swim club.

The media could not be loaded.
 I looked at so many mermaid tails on Amazon!! I was down to this one and another set that had a matching top to it. This one however was going to make it in time for the birthday so this one it was. I am so happy with it. It was my 7yr olds favourite gift. It’s so so easy to put on. I thought the fin would be seperate to the tail and maybe difficult to put the Finns on but it’s so easy. The Finn is built in to the tail and it’s got soft material to slide the feet into so my daughter can do this on her own with ease. She said it’s light in the water to wear and she picked up the skill instantly in the water. Super easy to use. I bought a bikini to go with it from target. We ordered the small for a 7 year old and fits perfect. We also tried it on our 5 yr old (just because) but the top of tail around the abdomen would come off in the water.
