Vesikaste Oy
I, and therefore Vesikaste practically has years, or rather decades of experience already with children’s swimming and water activities. At first it was a hobby in a swimming club and later a part of my physical education instructor job.

The company itself, Vesikaste Oy was founded in the beginning of the year 2009. At first the company offered different water activity services for kids and adults. The services have included swimming for babies and families, EasySwim swimming schools, swim clubs, specialized swimming instruction for people with disabilities, and private instruction for children and adults. Doing swimming instruction I noticed how kids’ swimming equipment was often of poor quality. I took different kinds of accessories on my swimming instruction lessons, and started to sell some proven products to others.

Three years ago on a trip abroad I saw a mermaid for the first time. It inspired me to bring mermaid swimming and mermaiding to Finland. Children now have less physical activities and many hobby sports can feel too serious. Mermaiding is supposed to be about joy, having fun, and enjoying water, while at the same time improving fitness. Myself I had always hoped to swim like a mermaid. It has come true at last. 🙂

I then began to look for a good manufacturer to make mermaid products. When one was finally found, I started to import mermaid tails and monofin flippers to Finland. Mermaid tails have now been sold to Finland in the Vesikaste webshop since 2017. Interest in Vesikaste’s mermaid products has risen elsewhere as well, so now the webshop is opened to Sweden.

Mermaid tails
The mermaid tails are made of breathable, quality fabric of 80% nylon and 20% spandex. The fabric is 4-way stretchable. Use the size chart to choose the correct size. You should not leave too much room for growth to make sure the suit fits comfortably. If the child is very slim and tall, it’s recommended to select a size based on waist and hip measurements and ignore the waist-to-floor measurement. Similarly to swimsuit fabric, the tail fabric cannot withstand mechanical abrasion. Try to avoid rubbing the tail against the poolside and floor.
Monofin flipper
The interior of the monofin flipper is made of flexible PVC plastic, making it durable and fracture-proof. On top of the plastic part there is a neoprene cover with sewn openings for feet and a small ankle support. The flipper is only suitable for swimming, not hopping or other kind of movement. The children’s flipper is meant for mermaid tail sizes 6, 8, 10, and 12. The adults’ flipper is designed to fit mermaid tail sizes XS, S, M, and L. If a child’s feet are over size 38 and adult-like, an adult size flipper should be chosen with the XS size mermaid tail. If a child’s foot size is under 30, notify this in the order details so I can send you a flipper with smaller openings. To swim like a mermaid, you a need both the mermaid tail and the monofin flipper! They are sold separately.

Suiting up
The mermaid tail and monofin flipper should be put on by the edge of the pool or beach, so that getting directly into the water is possible with the suit. The flipper is fitted in the tail one tip first, and then the rest of the flipper is put in place. Roll open the swimming suit and slip your feet into the flipper. There is a slot intended for feet, but you have to make sure that the feet are fully in and the ankle opening points upwards. The suit can also be put on by pulling the suit on first, then fitting your feet in the flipper and pulling the tail back down over the flipper. The feet openings are designed to be tight to keep the feet in place better when swimming! The flipper might be difficult to put on at first, but will be comfortable after a couple times of practise.

It is recommended to practise taking off the suit in water, so being released from the tail and flipper is possible when necessary. First, take one foot out of the flipper and kick the flipper off using the free foot. Then drop the suit down using your hands and swim out of it. Children must always be supervised by adults when swimming.

Watch a YouTube video on how to put on the suit and how to take it off in water.

After use
After using the mermaid tail and monofin flipper, please wash them with cold or lukewarm water and carefully squeeze the extra water off. Do not twist the fabric, for it might stretch and damage its structure. The product can also be washed in a washing machine with a small amount of mild detergent in 30°C. Don’t use bleach or softener products, and don’t iron or tumble-dry it. Dry it in a well ventilated place.
Safety instructions
IMPORTANT! Swimming with the mermaid tail requires good swimming skills (minimum 50 m), and it’s not a rescue tool. A child must be able to float on their back and belly, and to dive effortlessly before using the tail suit. On the first swim a parent must be in touching range, as swimming with the tail is different compared to using full legs. Therefore, swimming with the tail initially weakens swimming skills, as opposed to strengthening them. As one gets accustomed to swimming with the tail, it is easy to move fast with it and also get quickly too deep. This is something to remember especially when swimming in natural waters. A parent must ALWAYS supervise swimming children.
