Technical Information

Your practice
Beginners swim: young beginner swimmers who are starting to swim and need ease and comfort. For her, Nabaiji offers a wide range of swimwear that allow her to swim with products suited to swimming, but that also meet anatomical requirements
Y-shaped back: a swimsuit should focus above all on comfort, to allow you to perform your movements in complete comfort, without getting in your way or hurting you. That is why it is important to choose the shape of the back of your swimsuit carefully. A Y-shaped closed back swimsuit is ideal if you have a larger bust.
Material: 80% polyamide / 20% elastane. Chlorinated water can be harmful to swimsuits which are used repeatedly in the swimming pool. The elastane fibre that gives the material its stretch property and therefore makes it comfortable, is also very fragile when in contact with chlorine. If you swim occasionally this material will be fine for you. If you swim regularly or intensively, opt for a 100% polyester material.
Restriction on use
Not recommended for use on slides.
Score to compare the environmental impact of products
The environmental impact of the product is calculated over its entire life cycle and with different indicators. An overall ABCDE rating is performed to help you easily identify the products with the best environmental performance by comparing the same type of products with each other (t-shirts, trousers, backpacks). Decathlon is a committed stakeholder in this environmental labelling approach. Website: sustainability.decathlon.com Explanatory video: https://youtu.be/8t63KkRwn_8

Swimming costume review
Used for 2 to 8 weeks
This is a great swimming costume, pretty well made and designed for the price paid for it.
We had to go several sizes up to get a costume that fits my child. She is a tall 9 year old and in Decathlon is an age 14 already.
I bought this costume quite recently, but what I would say is that there is already some wear and bobbling around the buttock area of the costume. I’m not sure if it’s wear from swimming or washing or even sitting on the side of the pool, but it seems to be happening quite soon compared with other brands. Anyway, other than that this costume serves a purpose at a competitive price.
Should have read the previous review before...
Used for 1 week or less
As everyones else, after checking the size chart, I bought a size 6 for my 5 years old. It fit perfectly my 2 years old... What a joke!!!

Sizing is awful
Used for 1 week or less
Bought this in size age 10 for a small 9yr old,
It is ridiculously small, I would say this would fit a 5yr old. Sort your sizing out, now I need to go shopping again :(
Ridiculous sizing
Used for 1 week or less
Tried an age 10 swimsuit on my 8 year old, it was tiny! Got an age 12 which is still stupidly small. Please take this off sale and re do the sizes to stop wasting people's time. Should have read reviews first!!
totally wrong sizing!
Used for 1 week or less
I bought this swimsuit in size 8 yrs for my 5 year old daughter with the idea of her growing into it. It was too small! My daughter is not overweight, just slightly taller than average.
Small in size
Used for 2 to 8 weeks
This is very small in size. I have just bought an age 12 one for my small 8.5 year old. It won’t last much longer.
Sizing extremely misleading
Used for 1 week or less
As others have already noted, the sizing of this swimsuit is ridiculous. Having considered other reviews, I ordered a size 8 years for a just turned 5 year old - it's probably more suited to a 3/4 year old. While Decathlon does provide sizing information, the size 8 years (125-132cm) swimsuit is 4 cm shorter than the suit (age 4-5 years, 104-110 cm) it was supposed to replace. It's a shame as the suit is a nice design but it's impossible to order with any confidence.
Dreadful sizing!!!
Used for 1 week or less
Yet again Decathlon’s sizing lets them down. Bought an age 8 for a very slim 8 year old. Compared with another retailer’s 7-8 costume the decathlon one was 6cm shorter in the body!!!! I see in previous feedback Decathlon has tried to fob customers off with something about their sizes designed to fit global markets, i.e. implying that Westerners are too fat, I suppose! However the only 8 yr old who could fit this costume in an age 8 would have to be suffering from restricted growth/ malnutrition, and therefore highly unlikely to be in the market for a swimming costume!
Lovely swimsuit but tiny size
My daughter is a slim 6 soon to be 7 year old of average height. Ordered 2 costumes in size 7-8 and there was about 4" difference in length! This one was smaller than her current one age 5-6. LSo would recommend as lovely coloured costume but buy bigger.
Too small
Returned. Age 10 was too small for a small 8.5 year old
