So much fun! I am an adult woman and was afraid the tail might be too small for me, but the JL size fit fine, was even a little roomy in the waist. I'm very curvy and chose the size based on my hip measurement, as I was afraid I'd burst the seams if I went by waist size.

Swimming with this tail is a great core workout, and doesn't feel like exercise at all.

I got the tail and followed the instructions for putting the tape on (it really helps to have the monofin inside the tail). I laid the tail on my kitchen table, I folded the tape in half so I had a fold line as a guide, and only peeled back half of the tape backing at a time. I found it easier to adhere the tape to the back part of the fin first, then remove the rest of the backing to adhere the othe half of the tape to the front of the tail. I then used the blow dryer on it as indicated in the instructions and left the recommended extra tape along the edges and let it cure overnight.

The only issue I had (nothing to do with the tail itself) is that the adult (Nunui) monofin was way too big for me - I wear a size 3-1/2 and my feet do not make it past the monofin logo in the photo, so my feet did not even come close to that third strap(though it was fine for my friend who wears a women's size 10-11 shoe) so the fin would come off my feet while swimming even with the two other straps secured, and I found it difficult to splash the fin up out of the water (the photo showing the splashing fin is of my friend wearing the tail).

I bought another monofin in the child size (Keiki), and my feet again didn't make it past the logo, and only by shoving my feet in as far as I possibly could was I able to reach the (only) strap (barely) on my toes, so the fin still felt very floppy, but was not as heavy and was more maneuverable and I could lift it out of the water. Even though the fin was much smaller, the tail still fit okay over it and made the monofin less floppy; there was just extra fabric hanging over, which I can probably fix with some Velcro to close the bottom opening.

My friend and I had a blast taking turns using the tail and fin, and it is easy enough to out on in the water (I sat on the pool stairs to put it on, as once you are wearing it you pretty much have to pogo hop to get anywhere if you aren't swimming). The monofin is also very fun to use on its own and the foot section is neoprene, comes up over your ankles like a short sock, and is very comfortable.

I have swum everyday (weather permitting) with with the whole tail or with the fin alone; such a blast to use!

The media could not be loaded. This is very colorful and the elastic seems to be strong the good fun is super strong True to size
We got a medium to fit my child whom is 5"5 and wears a women size 7shoe Fits like a glove

I received this in a huge box with no packaging - just the fin and the cover thrown in the box. The fin seemed decent (despite some scratches and dings to the hard plastic), but the cover looked like it had been used. The fabric was pilling and the color was faded in these areas. I sent back and am waiting for a replacement. Will update review if opinion changes.

Update: I received a new fin in the mail in a package that one would expect. Company reached out to apologize for used order that was not filled by them directly and offered to send one directly from them. Item is a gift for Christmas.

Bought this for my four year old. Fin fits four year old feet/ankles. Velcro straps excellent quality. Fabric tail is way too big, but she just plays with it in the house. I will not let her wear fabric tail in pool until she gets bigger due to being too large. Fabric is excellent quality!!!! Worth the price! Would buy again for mermaid-obsessed daughter 😊

Love this tail! Fantastic monofin, wonderful fabric and print! Very comfortable, and well made! Got this for my 12yr old daughter. I wanted something that would last fit wise so got a medium instead of a small. It is a little loose around the waist in the water because it's long, but still fits and should fit for a while 😊My daughter loves everything about this tail!
