Chlorine resistant and the material is good

The price is right for chlorine resistant material and the swimsuit fits well on me. I went back to get a second pair but no size left. I bought another one the is all black and cost $15. I have not use it yet.

Size 8 Girls Costume - Small Sizing for age

Bought this for my 7 year old, and it is rather tight, she probably won't be in it for long.

good fit. stays in place

We are glad to hear you're loving this swimsuit! We hope you have a great day!


This suit certainly works but I was surprised to find that the almost matching one I bought for my girl was fully lined (front and back) while my adult version is not. I would have appreciated knowing this ahead of time. I do find it's cut rather low in the front. It works, but that feature isn't my favourite.

Super Confortable

J'ai changé pour ce maillot puisque je n'aimais pas la coupe de celui que j'avais précédemment (très limite au niveau de la poitrine et très bas dans le dos) J'adore celui-ci puisqu'il reste en place pendant ma demi-heure d'entraînement au crawl et aucun ajustement n'est nécessaire.


Merci pour votre critique, nous l’avons prise en compte et nous avons apporté des changements, grâce au commentaire de tous nos clients. Nous avons hâte de vous revoir lors de la réouverture. Je vous invite à consulter notre site internet, nous avons plus de choix et de grandeur.

Sizing inaccuracy

I’m a Speedo 38 so having read feedback ordered a 42 to be safe. Shocked to receive a 12 and 16 in size? Tried the16 on which wasn’t long enough in the body to cover my bust!

looks good but could be better

having worn now for a few times fit is ok but could be better - chafes on one shoulder and the other front side moves when swimming so end up having to adjust it whilst swimming - not had this with other costumes of the same make. holding its colours and shape well so far. good value for money.

Too small

Had to return it as it was far too small the sizes in Decathlon are ridiculous basically buy several sizes bigger than you expect it wouldn't have been as bad if I couldn't try it on in store but the changing rooms are closed.

Very comfy, doesn't roll up on itself and fab neon effect in pool lighting. Sizes v small as per all decathlon, I am a size 10 everywhere, but to not be over stretched and tight, bought size Large- decathlon reckon this a 14-16!!!

Good costume. Resists chlorine well and withstands a lot of use.

good fit, bright colours, great price

Picked this up in the sale and used it a few times now. Good fit, style as per another I bought last year but brighter design. The other one has lasted well so hopefully this will too.

great value, wearability and comfort

have used this costume when pools were open last year and again this week since reopened on 12/4/21 - dries easily, comfortable when swimming lengths (lots of them)

icon-circle-checkmark verified purchase

I’m a UK 8-10 and eventually settled on a size 16 in this one

Additional Product Information


Main fabric: 100.0% Polyester ; Lining: 100.0% Polyamide

Aquaresist technology

Products holding the AQUARESIST label are guaranteed to be resistant to chlorine. They will maintain their elasticity and are UV-resistant. For these reasons, they are recommended for regular or intensive pool use.


Main fabric: 100% polyester. Our engineers have developed a polyester-based fabric and replaced the spandex fiber with PBT fiber, which is stretchy enough to provide user comfort but, more importantly, is unaffected by chlorine. This PBT thread also has the advantage of being quick-drying. It only loses 3 to 4% resistance throughout its lifespan. Another plus: Even the brightest of colors will retain their colorfastness


This swimsuit has a front and back liningOBS: The graphics ALL IMO (8512180) only have the gusset (hygienic lining)

Product testing

The products labeled with AQUARESIST certification are tested under repeated cyclical loading in a pool of chlorinated water for 240 hours. No deterioration of elastic strength was observed throughout the test. Unlike a standard swimming product, the product remains intact.
