Women's swimwear

Prata om ditt varumärke
To make it easier to choose your swimsuit size, we have created our own size charts for each of our brands, which contain converted European size markings. When trying on a swimsuit, a swimsuit of the right size will fit snugly, but the swimsuit should not squeeze or press unreasonably. It is good to keep in mind that the material will stretch when wet, which will give the swimsuit more space from the first swim. When trying on a swimsuit, it is also good to make sure that the swimsuit does not restrict your range of motion or squeeze, for example when lifting your legs.
Generally, Arena swimsuits are slightly smaller than normal. So if you are considering between two sizes in an Arena swimsuit, we recommend choosing the larger one. Speedo's size markings correspond well to their size. Funkita swimsuits stretch a little less when used than other brands, because the suits are made of 100% polyester.
When choosing a size, please note that the models may differ from each other and fit each swimmer differently.

When swimming, it is important that the swimsuit stays on securely, even at high speed. Therefore, when choosing a swimsuit, you should also pay attention to the design and cut of the suit.
Our selection includes training swimsuits that can withstand heavy use. Training swimsuits are not supported and the cuts of the swimsuits vary by model. For more support in your training swimsuit, choose a swimsuit that ties at the back and can be tightened to suit you. You can find training swimsuits in our selection from Arena, Funkita, Jolyn & Speedo.
If you want a swimsuit that supports your body and needs support, for example, around your breasts, we recommend choosing a shaping swimsuit. Shaping swimsuits feature double fabric around the breasts and a supportive elastic band below the breasts. In addition, the suits also provide support for the midsection. You can find shaping swimsuits in our selection from Speedo, Arena and Funkita.

Men's swimwear

When choosing the size of men's swimming trunks, you can use the size chart found under each product. For men's swimming trunks, the size is selected by measuring both the hip and waist circumferences.
When trying on swimsuits that are the right size, they should fit snugly. However, they should not restrict leg movement. When trying on dry swimsuits, it is also good to remember that when the swimsuits get wet, they will stretch slightly.
Men's swimming trunks have a drawstring that ensures the trunks stay on securely. Depending on the model, the drawstrings are either on the inside or outside of the trunks.

Our selection includes men's swimming trunks from Arena, Speedo, Funky Trunks and Beco. The swimming trunks are available in three different lengths.
The shortest leg is found in briefs, which are a traditional style of swimming trunks. In briefs, the leg length varies from 7cm to 15cm depending on the model. The average leg length is found in boxers, which, depending on the manufacturer, have a leg length of around 27cm.
The longest leg is found in the jammer swimsuit. The long-leg model is popular with both fitness and competitive swimmers. The leg of the traditional jammer swimsuit reaches slightly above the knee. In our selection you will also find Mid Jammer models, where the leg is slightly shorter than the traditional model.
In addition to swimming trunks, the men's swimwear selection includes a wide variety of swim shorts from Arena and Speedo. The swim shorts have a drawstring waist and mesh inner briefs.

Children's swimwear

Prata om ditt varumärke
The sizes of children's swimwear are marked in the size charts in addition to the sizes used by the manufacturers, as well as the centimeter sizes commonly used in Finland. The additional information for children's swimwear also includes size charts specified by the manufacturer, which are a good way to ensure the correct size.
However, the best way to make sure you have the right size swimsuit is to try it on. A swimsuit that is the right size won't be tight or constricting, and won't restrict your movement. It should be snug so that it stays on comfortably even at high speeds.
If you are unsure between sizes, we recommend choosing the larger size for Arena swimwear. Speedo children's swimwear is true to size.

Our selection of children's swimwear comes in many different colors and designs. In addition to traditional swimsuits and bathing suits, there are also swim shorts and bikinis for children.
If you are looking for a swimsuit for the beach or on holiday, we recommend swimwear in bright colours, such as pink or orange. Neon colours, such as neon green and neon yellow, stand out best in dark lake water.
If your child needs a buoyancy aid in addition to a swimsuit, we have a variety of options for this. Depending on your child's swimming skills, we recommend choosing a buoyant swimsuit, a life jacket, inflatable hand floats or a swim belt. You can find more information about the options and how to choose a suit here.

Frequently asked questions about swimwear
Do all swimwear in the same category have the same size chart?
No. All swimwear from the same brand has the same size chart within a category, but for example, for women's swimwear, Arena and Speedo have different size charts. The size charts also differ between brands for men's, children's and youth swimwear.
What kind of swimsuit do you recommend for a swimmer with a long back?
For swimmers with long backs, we generally recommend Speedo swimsuits, as in our experience the sizing of Speedo swimsuits is better suited for long backs. Arena's thin-strap Team Challenge Solid swimsuit is also often a good choice for swimmers with long backs.
I'm between two sizes in the size chart, which size should I choose?
If it is an Arena swimsuit, we recommend choosing a larger size. Speedo swimsuits are true to size, so we recommend choosing the size that is closest to your measurements. When choosing a size, it is also worth considering that swimsuit models are different and their fits also differ from each other. For this reason, it is possible that the same size does not fit every model, even if the brand is the same.
How should a swimsuit be maintained?
Proper care of your swimsuit will extend its lifespan. Rinse your swimsuit with plenty of water, preferably cold, after each use. Machine washing is not recommended for swimsuits, but chlorine and dirt can be washed off with a mild liquid detergent. For more detailed product-specific care instructions, please refer to the swimsuit care label.
