1. Children’s swimsuits: What to wear for a race?

arena has designed a range of children’s racing suits based on the same innovation and comfort used for elite swimmers.

Featuring the same attention to detail and same eye-catching design as the swimsuits for adults, the children’s racing suits meet the needs of future champions. There is just one difference: the JUNIOR Powerskin models do not feature Carbon technology, which has been designed exclusively for adult swimmers.

2. What racing suits does arena market for young children?

arena has designed two special models for young swimmers taking part in races for the first time, Powerskin ST 2.0 JUNIOR and R-evo ONE JUNIOR, which are replicas of the corresponding adult models.


For boys and girls, this swimsuit is made from our special long-lasting elastic X-Raptor fabric with flat seams for maximum freedom of movement.

The Powerskin ST 2.0 JUNIOR CLASSIC is also available for girls featuring the same technology and fabric but not in a knee-length design. A conventional children’s swimsuit but higher performing.


For boys and girls. This is an extremely elastic swimsuit made from our special ONE technology, i.e. out of one single piece of fabric for maximum comfort and better hydrodynamics in the water.

The Powerskin R-evo ONE JUNIOR CLASSIC (for girls) and BRIEF (for boys) is available for both genders but not in a knee-length design.

3: Useful tips to recommend junior swimsuits

Racing suits fit differently from training suits because a racing suit is designed to fit tightly. Of course, young swimmers’ bodies are still growing, and everybody is different, so you need to suggest a size based on the physique, height, and muscularity of these very young athletes. Consulting the official product sizing chart and comparing the swimmer’s measurements with those given on the chart is always the best practice.

The right size is central. Even if boys/girls are growing, it is important to advise against buying a larger size, because a swimsuit fitting too loosely will let in water, not perform as effectively, and create friction while swimming.

4: When is the right time to buy a children’s racing suit?

Our junior racing suits range from size 6-7 years to size 12-13 years. In the case of very young swimmers, we suggest consulting a coach to decide the right moment to buy a child their first swimsuit.

It is worth remembering that in some countries, swimmers aged up to 10-11 can only wear POWERSKIN CLASSIC swimsuits in competitions, i.e. conventional swimming briefs. This is to allow younger athletes to focus more on technique and training without allowing any kind of technological innovation in materials to affect their performance. That is also why arena’s R-evo and ST swimsuits also come in Classic versions. The same material and the same features as the Powerskin Junior swimsuits but not in a knee-length design.

Bearing in mind, of course, that every growing body is different and the physique, height and muscularity of young athletes needs to be taken into consideration, generally speaking both young boys and girls around the age of 13 should consider buying a swimsuit in an adult size.
