Both in the factory and in our warehouse we check the products for damage. If we miss something, we will of course solve this with you immediately. Check immediately after receiving your order for damage. If this is the case, please inform us within 3 days of receipt.

If you have not yet received confirmation that we have shipped your order, you can always make an adjustment to your order.


Other questions about the AirTrack

What is the difference between the old Airtracks collection and the new model?

For the new collection we looked at how we could make our Airtracks even better in all areas. That is why we made the side of thicker PVC to extend the lifespan. The suspension has been improved by using even better โ€œdouble wall fabricโ€, the core of the Airtrack.

And we looked at how we could make the Airtrack even more beautiful. For this we switched to a new production method that is also used by top brands in the SUP industry. This method ensures a better finish. An additional advantage is that the connection of the different parts has become much stronger, which means we can now give a 2-year warranty.

Ultimately, we looked for a way to implement all these improvements and still make the price more accessible so that more kids and adults can enjoy the many benefits of an Airtrack . The solution for this was found in a collaboration with 3 other serious suppliers of Airtracks that are active in other countries. Through this collaboration, we can significantly reduce the cost price of the Airtracks, which in turn has a positive effect on the prices.

There are many suppliers for AirTracks, how do I choose the right one?

Always check the company where you want to buy. There are a number of companies active in the Netherlands that have been around for years and where you can therefore safely order. However, there are also a few providers that are not clear about, for example, the delivery time or that have it shipped directly from Chinese sales platforms, which means that you still have to pay VAT and import duties upon receipt and cannot claim any warranty.

Therefore always check in advance how long the website has been around (www.sidn.nl) and whether they have real reviews on e.g. Google, Facebook or Trustpilot. Reviews on your own site say little, anyone can put them there.

What about the delivery time on the AirTracks?

View the description of the AirTrack in question. This clearly states whether the AirTrack is in stock. If this is not the case, it will state the next date on which new stock will arrive and whether there are still AirTracks available from that stock. You then have the choice to place your order now, which guarantees your reservation, or to wait until the specified date and order at that time.

Why are your AirTracks cheaper than many other suppliers?

We get this question a lot. We like to turn the question around, โ€œwhy are they so expensive?โ€ ๐Ÿ˜‰

The production of AirTracks is becoming more affordable. However, many suppliers still hold on to the old price level. Some still work with an older and more expensive production process, which means they have to keep their prices high. In addition, there are also suppliers who can deliver cheaper but choose a higher profit because many people are still willing to pay their high prices.

Just like we have been doing for several years with the mermaid tails, we choose to deliver high quality AirTracks for an affordable price.

Are your AirTracks waterproof?

Yes, you can use the AirTrack on the water without any problems.

Is there a difference between the front and back of the AirTrack?

Yes. All Airtracks have Velcro on one side. This allows you to attach an extra AirTrack, for example. The other side has a line across the middle.


Other questions about the mermaid tail

When can my child swim with a mermaid tail?

We recommend that children only swim with a mermaid tail if they have obtained diplomas A and B. In addition, there must always be adult supervision.

How do I maintain my mermaid tail?

The best way to properly maintain your mermaid tail is to rinse it with cold water after swimming and let it dry thoroughly before storing it away. You can machine wash it on a cold setting, but it will shorten its lifespan.

How do I put on the tail?

The easiest way to put on the tail is when it is dry and your feet are wet. You roll the tail all the way up until you see the black fin. You sit on the edge of the pool and then you put your feet in the monofin and roll the tail up over your legs as far as possible. You can do the last part while you jump in the pool.

I would like to order some tails for my swimming school, what are the options?

Please contact us for this.

What shoe size are the monofins for?

The tails in sizes 6 to 12 are supplied with a monofin that is suitable for sizes 31 to 38. From size XS the tails are supplied with a monofin that is suitable for sizes 35 and larger.

How do I choose the right size?
