That’s why I’ve decided to tell you a bit about the function of swim caps in this guide, the different types available, and which swim caps are the best. Finally, I’ll also give you my clear recommendation on where you should buy your new swim cap.

“Great to have a swim cap with plenty of room for hair without it riding up while swimming” – (Gitte C.)
“Really great swim cap. Doesn’t pinch, and my hair stays dry. It’s a beautiful colour too.” – (Asma D.)
For some, the bubble design may just be an aesthetic choice that stands out from the ordinary swim cap, but there is actually a deeper purpose behind the design. The small bubbles create tiny air pockets on the inside, trapping air warmed by body heat.
This creates a natural barrier against cooler surroundings and low water temperatures. Working much like a wetsuit, the air in the small bubbles comes into contact with the cold water first, creating a protective layer so the cold environment does not come into contact with your forehead and scalp.
That is why Larunda Bubble is also particularly well suited for open water swimming and in pools with colder-than-normal water temperatures. The swim cap offers extraordinary durability and thermal insulation compared to other swim caps. So if you tend to feel the cold easily, the Larunda Bubble is definitely for you 😉
“Fantastic swim cap, would buy again” – (Christian P.)
“Fits my head perfectly.” – (Brian N.)




It may not always feel inspiring to wear a swim cap – especially for kids. They can feel tight, warm, or just boring to wear. Nonetheless, wearing a swim cap is a great idea, whether for swimming or protecting hair from damage. They simply provide much better hydrodynamics in the water, resulting in higher speed.
That is also why it is much easier to get kids to wear a swim cap if you appeal to their imagination and curiosity. After all, what could be more colourful and fun than adding a personal touch and turning into a fish or a shark in the water? It makes things far more fun than wearing a plain – and sometimes dull – swim cap.
“Fits my 5-year-old perfectly. Dry hair, no water in the ears” – (Carmen B.)
“Super cute swimming cap of really high quality.” – (Simone L.)
“Highly recommended! Fun swimming cap that my daughter absolutely loves, thank you!” – (Maria D.)
If you are a woman looking to express your femininity, a pleated swimming cap is a fantastic option. And here, this Watery Maxwell pleated swimming cap is the best choice.
It features a polyester outer shell and a soft rubber lining on the inside. This ensures it fits comfortably and securely on your head while protecting your hair from getting wet.
Due to the pleating, it is not suitable for dedicated swim training. However, for leisure use in the pool or at the beach, it gives you a lovely feminine look while keeping your hair dry.
Plus, it comes in black, white, light blue, navy, pink, and red—allowing you to pick the exact style that suits your personality.
“Very good fit” – (Emma R.)
“Fine product and super service” – (Mette K.)
If you are a competitive swimmer chasing the absolute finest margins, you need the Watery racing swim cap – Signature Dome on your head. It is without doubt the absolute best and fastest racing swim cap on the market!
First and foremost, it sits extremely well on the head. It is constructed from different panels across the entire swim cap, ensuring a snug fit everywhere on the head. And the better it fits, the more it reduces drag.
One of the best features is its cut-outs at the ears and the neck. The ear cut-outs allow you to hear the start signal more clearly. And the neck cut-out makes it much more comfortable and minimises drag since it doesn’t create folds.
Overall, not a single millimetre of excess silicone has been used. This plays a huge part in making it so fast!
To ensure the most streamlined fit possible, it is important to choose the right size. So before buying, please refer to the size guide below:
“Fits snugly and keeps hair completely dry. Love it!” – (Kasper S.)
“Great value for money. Has quickly become my favourite for training!” – (Rie B.)
At first glance, you might think a swim cap is just a swim cap. But that is not quite the case in reality. Below, I will cover the different types available so you can find out which one best suits your needs.
The most durable swim cap you can get is a silicone swim cap. Silicone is an incredibly flexible material that can withstand being stretched a lot without breaking.

Compared to other rubber materials, silicone is relatively expensive. Therefore, a silicone swim cap also costs more than swim caps made from other materials. On the other hand, it also lasts a very long time.
A latex swim cap is often very cheap, especially compared to silicone ones. However, being cheap comes at a cost, as the durability is genuinely not very good.
Latex can be stretched an incredible amount, but it also tears easily. And if you get even a tiny tear in your latex swim cap, it is ready for the bin. The rest will simply rip as soon as you put it on your head.
A racing swim cap is usually made of silicone. However, what sets a racing swim cap apart from a standard silicone cap is its cut, panels, and fit. All of these factors have an impact on your speed in the water.

Racing swim caps come in specific sizes. They are also quite expensive. On the other hand, you will only be using it for competitions, where 0.01 seconds can mean the difference between 1st and 3rd place.
Swim caps for long hair are essentially just like standard swim caps. They are simply slightly roomier inside, allowing space for your long hair. If you have long hair and have ever tried putting on a regular swim cap, you know just how difficult it can be.

And that is exactly what swim caps for long hair help with.
With a floral swim cap, you add a splash of colour to the otherwise plain swim cap. A cap like this features a floral design, ensuring you won’t look like everyone else at the swimming pool.

Due to the floral design, a flower swim cap is only intended for casual swimming. It simply creates too much drag if you plan on using it for proper swim training.
If you want to accentuate your feminine side, you can benefit from using a pleated swim cap. Unlike standard swim caps, which are completely streamlined, the pleats on this type of swim cap give it a more feminine look.

Pleated swim caps are made of polyester on the outside and rubber on the inside, ensuring a secure fit on your head. However, due to the pleats, there is quite a lot of water resistance in the swim cap.
It is therefore primarily suitable for casual swimming in the pool or at the beach, or for leisurely dips.
A bubble swim cap is the kind you typically see worn by older ladies at the pool. And with good reason. They are super comfortable to wear. They protect your hair well without pinching your head too tightly.

The “bubble” name itself comes from the small bubbles distributed across the entire outer surface of the swim cap. Each bubble contains a small amount of air, which helps boost insulation so your head underneath doesn’t get cold.
There can be several good reasons to swim with a swim cap. But the most common purpose among regular fitness swimmers is to protect their hair from chlorine. Chlorine really isn’t particularly good for our hair.
In addition to protecting your hair, a swim cap also reduces water resistance when swimming with your head underwater. Hair creates quite a lot of drag, so by tucking it away under a swim cap, you can actually swim faster without exerting more effort.
And a swim cap also helps you keep your head warm in the water. For most people, this isn’t an issue in indoor swimming pools. But if your circulation isn’t what it used to be, a swim cap will help maintain body temperature in your head.
Last but not least, a swim cap also helps you keep your hair in check. Wet hair is just as unruly as loose hair in windy weather, so when you tuck your hair away under a swim cap, you avoid getting it in your eyes.
Whether you often visit the swimming pool or only go once in a while, chlorine is by no means good for your hair. Chlorine actually dries out your hair, leaving it dry, tangled, and over time, not looking its best.
That’s why it’s a great idea to use anti-chlorine shampoo and conditioner when you shower after a swim in the pool. Anti-chlorine shampoo is specially formulated to wash all the chlorine out of your hair. And the conditioner helps make your hair both soft and shiny, which chlorine is otherwise all too good at undoing.
Anti-chlorine shampoo and conditioner are suitable for both short and long hair. And I recommend using it straight after every trip to the pool—ideally immediately afterwards!
If you want to protect your hair from becoming dried out, tangled, and dull-looking, you can buy anti-chlorine shampoo and conditioner here.
