Too small!

My daughter is age 10, so I bought the age 12 expecting it to be a good fit. It's tiny! She couldn't even get her legs in. I checked with store staff which size to order and they did not mention how small this is. This is now sold out in other sizes, and I can't even try the ladies either because that's also sold out. So a warning .... buy BIG at Decathlon in children's wear even if your child is skinny!

Too small

My son just turned 9 so we bought size 10 (as trisuits normally last 2 years). This was so small that he put one leg in but we couldn't get the other leg in. It's tiny. When it was on the table, the width of the trisuit is width of the smaller side of A4.

Hi Sara,

Thank you for your review. We're glad to hear you had a positive experience with this product. We designed this kid's trisuit to look good and be value for money. It makes for a great first trisuit for kids wanting to experience any sort of multisport event, like a triathlon. Its designed with a long pull tab to make zipping the suit, and a chamois appropriate for race distances catering to kids.

If you are looking for other products that are needed for racing, do check out our website Alternatively, head down to our stores where our sporty team mates would be happy to help you in making sure your child has everything he or she may need for their first race.

We hope to see you at our stores soon!

Much love,

Great product, value and overall quality!

My son is 12. He is tall and skinny. And he ares age 14 size. Fits perfect ! We have been buying stuff from decathlon since they first arrived thus we know we have to always get one size up. As their sizes runs smaller. They deliver great overall quality and price ratio. My son loves it. Feels like a second skin. Dries fast and great ventilation

Hi Jacky,

I am delighted to hear your review on the Trisuit. This Trisuit just came in about a month ago and we are waiting for more triathlon equipments to come in for this year. Hope you find the other products as useful as well and do let us know if you have something that you are looking for and we do not have it now. 

Your friendly Sports Leader

super Einteiler

Mein Sohn hat den Anzug die ganze letzte Saison getragen. Letztes Jahr hatte er die grösste Kindergröße. Jetzt ist er 13,164 m und 42 kg.der Kinderanzug zu klein. Leider ist der Herreneinteiler in s aber noch viel zu gross. Schade.

Genau was ich wollte

Preiswerter Anzug für Kinder, entsprach den Anforderungen

Schön Anschmiegsam

Der Anzug passt sicher super dem Körper an auch beim schwimmen und Radfahrern fühlt er sich gut an mein mein Sohn. Er ist 6 Jahre alt zum Glück hatten wir die Größe 140 bestellt der passt jetzt gerade. Bisher nur beim Training benutzt bin gespannt auf den nächste Wettkampf in 3 Wochen.

Sehr gute Passform

Unser Sohn ist begeistert, er zieht ihn im Wettkampf sehr gerne an. Er passt optimal, schmiegt sich an, so dass im Schwimmen kein Bremsgefühl entsteht. Wir werden ihn wieder kaufen.

Super zufrieden

Hab einen Einzeiler für meinen ersten Wettkampf gebraucht. Einer von Amazon ging direkt zurück und dann kam dieser. Passt perfekt und fühlt sich super an. Ist bequem und man spürt ihn kaum. Werde mir auch noch den mit Ärmeln bestellen


Artikel ist toll, wir hätten ihn allerdings schon früher gebraucht. Lieferzeit war leider sehe lang, obwohl bei Bestellung 2-3 Tage stand.

Calidad y precio bueno

Buena calidad precio. Cumple su función a la perfección. La cremallera podría ser un poco más larga pero es un simple detalle por mejorarlo

Tallas muy pequeñas

Después de marcar como novedad el producto procedo a ir a la tienda y no hay pues se suponía que si... Pido mediante la web y al día siguiente me cancelan el pedido pues ya no hay(decían que si) . De nuevo he de ir tienda que me devuelvan mi dinero. Me mandan un mensaje diciendo que ya hay en stock y nuevamente realizo el pedido, este tarda 1 semana yo pido una talla 10 para que le este "grandecillo" 32kg y 123cm pero no le pasa de la gusta el producto pero no la manera de gestionarlo ni el tallaje marcado.

Why wear a trisuit?

For swimming, cycling and running in the same suit, the trisuit is a staple. Its benefits: dries quickly after swimming and is comfortable for cycling thanks to a pad that does not hamper your run.Triathlon suits are worn like cycling shorts: with no underwear.

Trisuit, triathlon suit, triathlon trisuit ... are there differences?

None! It's the same type of triathlon outfit, a 3-in-1 suit: it's up to you to use the term you prefer. Just make sure you don't confuse it with the neoprene suit that provides buoyancy and warmth for the swimming portion

Should i put on an additional suit to swim?

Yes … and no.The trifunction suit doesn't provide thermal protection, but the neoprene suit provides buoyancy, an asset for the swimming portion. Good to know: The French Triathlon Federation forbids isothermal swimsuits when the water temperature is above 75°F and makes them compulsory when the temperature goes below 61°F. Between 61 and 75°F, it's up to you.
