It has been a dream for many girls and boys to be a mermaid or merman, and now your dream can come true.

With a mermaid tail from Fin Fun, you'll easily be able to navigate the water, whether it's down, forward, up or down. When you're wearing the mermaid tail, you'll feel how fast you speed through the water with the flick of the tail.

This mermaid fin from Fin Fun has a design that consists of several shades of purple - a combination that looks magical. The interplay of colours creates the illusion that the material looks like real fish scales.

In addition, this set is simple to put on and take off and is a great way to learn to swim. Even as an adult, it's great for training multiple muscle groups such as your back, abdomen and legs. Likewise, it also improves your swimming ability, but in a more fun way.

When you buy this set, you get the monofin itself and the suit. It is available in sizes 6 years to 12 years.

The mermaid tail itself is made from a combination of polyester and elastane/spandex, which ensures that it is comfortable to wear and flexible at the same time.

Features of the Mermaid Tail from Fin Fun:

  • This mermaid tail can be used for swimming.
  • It can be washed in the washing machine (In cold water).
  • Improve your swimming skills.
  • Can help train different muscle groups.

How to put on the mermaid tail:

When you receive your mermaid tail, you'll quickly realise that it's a wide monofin with room for both your feet. Once you have your feet in, you'll also notice that it's super snug.

Once you've got your feet firmly placed in the monofin, it's time to put the suit on. You take the suit and pull it over the monofin and then up towards yourself, the suit should wrap around your body around your bum and hips.

As your feet are almost locked down in the monofin, you need to use your legs to swim by taking them up and down.

Complete the outfit:

The mermaid tail can easily be worn on its own, but also goes perfectly with Fin Fun's own top for girls, which you can see right here.

Of course, at Watery.dk we also have a pair of swim goggles that we think would go perfectly with the colour theme, you can see our suggestions here.

Precautions when using the mermaid tail:

The mermaid tail is not fragile as such, but as the mermaid tail is made of relatively hard material, it can break if not treated with care. Therefore, it is not recommended that you do not stand on the monofin itself, as it can damage the cover and in the worst case break the fin.

Bikini is not included with the purchase of this product.

        Good service

        There was good service and fast delivery. However, experienced that the tails we have ordered were large in size in terms of size marking, but by measurement we have been able to find the right size for our swimmers.
