Who are our swimsuits for?

Our boys’ swimsuits are for any level of swimmer from beginner to professional. Our swim shorts offer a lot of support and freedom, allowing every young swimmer to move through the water comfortably and stylishly.

Many of our swimsuits are equipped with quick dry technology which gives you the freedom to be constantly on the go on your holidays and in the pool day after day.  

We supply our boys’ swimsuits for kids up to 15 years old after that they move into adult sizes.

Choosing the perfect swimsuit for your kid

When choosing the perfect swimsuit for your kid, you don't want to make compromises between affordability, comfort, and style, and with Decathlon, you do not have to. We supply great quality, comfortable swimwear at affordable prices so you don't have to worry about spending that extra money on a few treats for the kids. 

Whether you have a future Olympic swimmer at home or an energetic water baby, we know you will find the perfect swimsuit for them on our website. We offer a wide range of swimsuit styles and designs ranging from blue long sleeve shorty swimsuits to classic shorts fit and even jammer shorts. So whatever your boys’ taste in clothing is, we can guarantee we’ve got the perfect piece to suit them.

We know swimsuits can be worn all day, especially on holiday, so the perfect style is essential. That’s why we stock our boys' swimwear in as many different styles, colours, and designs as possible. As well as that we can offer cool accessories to match your swimsuit of choice. From bright and eye-catching pieces to more subtle and simple designs, we have it all.

Choosing a comfortable swimsuit for your kid is the best way to ensure both you and your kid’s poolside days are as enjoyable as possible. Stretchiness and support are two important factors in the comfort of a swimsuit, but fixtures and seams should also be considered for durability and resilience as much as comfort.

At Decathlon, many of our boys’ swimsuits offer sun protection and chlorine protection due to the high-quality materials that are used. This can give you peace of mind that your kids are protected from the sun's harmful rays while they have fun by the pool.

The importance of choosing the right swimsuit

Choosing the right swimwear for your boy can be difficult but here at Decathlon, we have tried to make the process a bit easier for you. We offer a 365 day returns policy on all of our online orders. So if you end up picking out the wrong swimsuits you can return them to us with ease. 

Just like adults, kids love to express themselves through their clothing. This is why the colour, pattern, and style of boys' swimwear are hugely important when choosing the right swimsuit. The best way to ensure your kids are happy with their choice of swimsuit is to let them browse our website with you and pick out the pieces that jump out at them. Trust us, you want your kid to be happy in their swimsuit and not miserable when you take them to the pool or beach.

If you are ever unsure about which swimsuit is the perfect fit for your kid, you can always reach out to us online or visit us in-store and an expert member of our staff will be happy to help you. We hope you enjoy browsing our vast selection of girls’ swimsuits and bikinis online and that you enjoy your next swim.

The use of functional and durable fabrics is another important factor that goes into choosing a kid's swimsuit. The materials need to be both lightweight and flexible since kids spend extended periods of time in their swimwear in summer.

As well as durability, the right fit when buying a boys’ swimsuit is essential. However, this is easier said than done as they’re at the age where they are constantly growing. This is where Decathlon’s 365 day returns policy for all online orders comes in handy. You can order the swimsuits with peace of mind that they can easily be returned.
