Mermaid Monofin - Swim Fin in Kid and Adult Sizes

We purchased this to fit inside of a mermaid tail and it fits perfectly. The quality of the fin is excellent and great to swim with

Great product and service. My 7year old loved the necklace . Thank you

Be sure to read up on the proper use of this before using. My son nearly drowned using this for the first time. Product description was vague on sizing. He is 4 foot 11 and 12 years old so I wasn't sure what size to get him. Technically he can be in an adult size but safely should have been in a child's size. Fin is heavier in the water and it dragged him down when he tried to stand up in the water. He learned through trial and error that the best way to stand up on a shallow pool floor is to lay flat on your back to cause the fin to float up and then stand up. After that, he just had fun with the adult one instead of the child one. Easy to put on. One tip: lube your feet to make it easier to slip on. I learned that from a show called Merpeople. Good tip. Easier to slip off when wet that way.

Grand kids love their new toy!

The mermaid tail is made with very durable materials and works well

This is just not a viable mermaid tail. I’m honestly so sad I didn’t do more research before deciding on a monofin brand. The combination of how rigid the tail is combined with the flimsy scuba fabric pockets for your feet is so ridiculous. If you have ever swam in fins this feels nothing like that. This feels like swimming with a tray attached to your feet via socks. I’m a lifelong competitive swimmer and lifeguard and I was winded within minutes of trying to swim with this contraption on my feet. I hope the company who makes these stops making them.

I usually swim with a Finis Rapid, but wanted something more for fun that wouldn't give me foot cramps. I've used the different versions of the Finfun monofin, but couldn't get enough power from it and felt like I was just wearing a wobbly sock. The SunTail fin has the thicker plastic fin, so I figured power would be much better (and it is). Some issues though: Like the Finfun, the main thing you're pushing against on the downstroke is the neoprene, which stretches and isn't super efficient. The straps on the SunTail (this fin) are a major improvement for me over the FinFun, but I practically have to push my toes against the mid strap to make use of it. The low strap is too far down for any size feet (I wear a 43 usually) and doesn't do much. Friends who have smaller feet and tried it couldn't reach and found the fin to be uncomfortable to swim with. I wish the mid strap connected to the fin between the feet and offered a better method of tensioning the velcro strap. After maybe 8 hours of use total and putting the fin on/off a dozen time, I noticed a split in the seam between the ankle cuff and main section. Easy enough to sew, but it makes me uncomfortable for future failures on more important spots. All in all, I'm pretty happy with my choice, though it really will just be a "comfy loafer" kind of fin for the pool. I'll probably take a crack at modifying it myself and moving the strap to hold my feet better. Fits FinFun and SunTail skins just fine. UPDATE: SunTails reached out after my review was posted and sent a replacement foot pocket almost immediately. Haven't used the new one yet, but I appreciate the immediate attention. As they mention on the listing, the fins are covered against defects for 1 year.

My daughter loves it
