Frequently Asked Questions

Are mermaid tails safe for swimming?

In short, they can be dangerous. If your kid isn’t an expert swimmer, mermaid tails can be tricky to use at first. They restrict the use of your legs, making it difficult to stand, and they require a bit of technique to swim with them properly. It’s highly recommended that if your children aren’t expert swimmers, they should use the mermaid tails with the tip of the tail open. Most importantly, you should always supervise your children while they’re swimming with mermaid tails, and they should never be used in open waters.

What is the best mermaid tail material for swimming?

Like most swimsuits, you want a lightweight material that will dry quickly. The silicone tails might look more realistic than those made out of lycra, but silicone is extremely heavy, and it’s not the best option for beginner swimmers. Instead, opt for fabrics like lycra, polyester, and spandex.

Do you need a monofin to swim in a mermaid tail?

It depends. If you’re a seasoned swimmer and want the power to propel yourself faster, then a monofin will help you achieve it. Some mermaid tails come with a monofin. Others come separately. However, most mermaid tails can be used with or without a monofin. Look for those with open bottoms and tail zipper closures to easily insert or take out a monofin, depending on your activities. Kids can also use flippers that are better for beginner swimmers and will still give a similar effect.
