The Junior Swimwear page brings together swimsuits for young swimmers: girls' one-piece swimsuits Arena, Speedo and Nike, two-piece swimsuits Protest and Hummel, jammers Arena and boys' shorts, and swim vests Zigzag for learning to swim.

From the first swim at the club's swimming school.

Learning to Swim

For little ones discovering water, the swimming vest, like the Zigzag neoprene one, helps them float while keeping their arms free to learn movements. It never substitutes for adult supervision. From the very first lessons, a fitted swimsuit stays in place and allows for free movement: a one-piece for girls, briefs, boxers, or jammers for boys, depending on the pool's rules.

Swimming on the Site

Swimming also includes:

All the equipment is gathered on the swimming page.

Training at the Club

Young club swimmers train several times a week: a chlorine-resistant swimsuit lasts much longer. Girls' swimsuits with a racerback, like the Arena Pro Back or the Speedo Medalist, leave the shoulders free for freestyle and butterfly. The children's jammer from Arena outfits boys for training and competition. Two-piece swimsuits and swim shorts, like the Protest Culture, are reserved for the beach and leisure.

Choosing the Right Size

A junior swimsuit is selected based on age and especially the size in centimeters indicated by the brand. It should be fitted without being tight: if it's too big, water gets in. Children grow quickly, so check the size each term. The swimming cap, required in many pools, and goggles, which protect the eyes from chlorine, complete the equipment. Rinse the swimsuit in clear water after each session.

Good Deals

Good deals can also be found in the good deals, promotions, clearance, sales, and Black Friday. The new arrivals showcase the latest collections, and items shipped in 24h are prepared and dispatched within 24 hours. The highlights of the year follow a stable order: the Black Friday at the end of autumn, the end-of-year celebrations, the winter sales, the French Days in spring, then the summer sales and back-to-school.

Frequently Asked Questions

At what age should a child be enrolled in swimming lessons?

Babies discover water from just a few months old, accompanied by a parent, and swimming lessons often start around four to six years old, in group lessons or at a club.

Jammer, boxers, or swim briefs: what to choose for a boy?

Swim briefs, which are very free, are suitable for the pool and training. The boxers cover a bit more, and the jammer, which goes above the knee, provides support and freedom for club swimmers.

Are swim shorts accepted in pools?

Most public pools prohibit loose swim shorts for hygiene reasons. Boys must wear a fitted swimsuit, like briefs, a boxers, or a jammer.

What swimsuit is suitable for a girl swimming in a club?

A club swimmer chooses a one-piece swimsuit that is chlorine-resistant, with a racerback or crossed straps to free the arms. Training models from Arena and Speedo maintain their shape despite frequent sessions.

Is a swimming vest useful for toddlers?

The neoprene vest, like the one from Zigzag, helps toddlers float while keeping their arms free to learn movements. It builds confidence but never replaces adult supervision.
