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 disturbing 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.
Use restriction
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 score (ABCDE) is attributed to help you easily identify the products with the best environmental performance by comparing products of the same type with one another (T-shirts, trousers, backpacks, etc.). Decathlon chose to apply this voluntary environmental labelling scheme. Website: sustainability.decathlon.com Explanatory video: https://youtu.be/8t63KkRwn_8

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!!!

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
Seriously misleading size hiide
Used for 7 to 12 months
Sizing guide a joke, ordered 10years for a 7year old would be more suited to a 5 year old. Surely decathlon have a responsibility to put correct labels/sizes on clothing.
Response of the brand
Dear Julie Ann,Thank you for your recent feedback. We are sorry to hear that you found our swimsuit too small. We are working on new size template for children's clothes to make it more up to today's market and more regional as Decathlon sells the same models around the world.Also, to help to choose correct size we added to each product page, just above the box with size selection blue colour link "find your size" where you can see chart with metric and imperial height linked to each size. In addition to that we made visible customer's feedback where you can check opinion from customers about the size who already bought the product. We are working also on this tool development to make sure in the future everything is in one place and it should help to choose correct size.Please return this item to your local store or use the online procedure for full refund or exchange.Once again apologies for any inconvenience caused.Kind regards  KORNEL
