Mermaid Monofin Swim Flippers
- The Sun Tail Mermaid monofin has been engineered and designed to move the swimmer efficiently through the water using the dolphin kick.
- Our products are built to last. We offer the highest quality monofin for swimming! Our monofins come with a 1-year promise with free replacements for rips, tears, and breaks.
Newly redesigned foot pocket for increased comfort and durability
Our newly redesigned monofin foot pocket includes thicker neoprene, providing more comfort and durability. Our redesigned plastic fin is virtually indestructible.
- The fin's realistic ridges add beauty and give you more propulsion through the water than other fins.
- An adjustable Velcro strap over your fit holds your fit securely in place to provide comfort, stability, and control of movement in the water. This makes performing fancy mermaid turns and flips much easier!
- Our foot pocket separates your feet so your ankles don’t rub together.
- Soft fabric cushions your feet so they don't rest on plastic like most other fins.

- Only our Sun Tail Mermaid monofin comes in a rainbow of ten fun colors to match your mermaid tail or leggings!

My daughter and I visit the pool about 2-3 times a week. So needless to say we swim ALOT. Finding something that fit good, didn’t chafe and durable was harder than it sounds. However after ordering this mermaid tail I can say without a doubt this product has hit the nail on the head with all 3. All the tails before would far apart or slip off her feet while swimming. This one is rigid yet comfortable and stays on her feet no matter what she does.

We used these mono fins in a tail that we had purchased separately. They were used in a professional photo shoot that made dreams come true! Fantastic!

I like how big and strong the tail / fin is.The detachable neoprene foot part holds to the hard fin with 3 Velcro straps and can be dried separately.On using it I noticed that ankle support was missing, and a lot of leg movement did not transfer to the fin beating, but instead overstrained my ankles.Until I find a way to secure the fin to my ankles, I won't be able to get the benefits of monofin swimming for my back and abdomen. I'm a bit sad but hopeful that I can find a system.

My daughter was not able to put on the mermaid tail and I wrote an email to the company for help. They get back to me not even an hour later with many tips and things to try before returning the item. Turns out the tips worked perfectly and my daughter is now a very happy mermaid! :)

My daughter loved swimming with the fin! Unfortunately after that first day (2 hours) the fabric has ripped. I’m not sure who to contact for a replacement or refund. It’s fun, but a little expensive for a single use itemUpdated: I reached out to the company and was able to get a replacement quickly thanks to the 1 year warranty. They sent a replacement and even suggested tips to keep the tipping from happening again

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.
