Hi WeyLee Oi,

Thank you for taking time to review our BASIC RUNNING SPORTS BRA BLACK. It is unfortunate that you had a bad experience with this product. 

However, do note that this product is a 'compressive bra' and for some, the compression may feel a little tight. We would advise you to consider a size bigger for comfort (We've opened another size up - XL for the latest collection) or explore our 'classic bra' options which is closer to the comfort of an 'everyday-wear' bra, yet providing the support needed for your runs. ( or

Should you require further assistance, do come down to any of our big stores and approach our Running Sports Advisors. we look forward to more of your reviews and sharing!

Yours Sincerely,
Lovely sports bra top

Great item and bargain!

There is no padding.

The picture looked like its well padded but the item I got is not. How can this be used for running without pad support. Its also smaller than usual size.

Best ever

So comfy and light

I got both colours . In this pink and the black. Both were is size XS. When it arrived, i found the tags and it did said something like "YOUNG WOMEN" OR "TEENS' OR "KIDS SPORTS BRA" I was lucky enough to still fit in this size and still wear it . It was quite stretchable.

First of all, thank you very much for your feedback on our products. In Decathlon, we believe that to get this kind of information from our users is the best way to improve what we are doing.

I have taken note of the size issue with our BASIC RUNNING BRA NEON CORAL PINK, I will forward this to our product engineers for them to take this into account for their next product design so that sizes reflect the item correctly.

Again, thank you for the feedback, don't hesitate to come down to one of our store in Singapore. It will be with big pleasure that we will welcome you !

Sports bra

I ordered this sports bra and is too small I’m a 6-8 and the small is ridiculous feels as if my shoulders are going to be cut from wearing it! Saw that a new resized one came out just after I’d ordered mine The same day and I don’t know why I wasn’t sent this version rather than being sent the one that decathlon knew had sizing issues. Now I have to go through the hassle of printing out a return form label stand in a queue for my bra to be exchanged, very inconvenient. Why is this bra still online if you know there are sizing issues, it will just cause more inconvenience for other people. I feel like throwing the bra away and just going to marks and Spencer’s and buying one there, more money but less inconvenience.

Hello Lauren,

I am sorry to hear that this product has not fitted correctly. We are aware that this product does have sizing issues and as a result there is a newer version as you mentioned. The reason for continuing to sell our remaining stock is that the product has a 4/5 review from our customers. In the incident of a product being unsafe or having a rating of less than 3, we will block the item from being sold immediately. I appreciate that this does not help with your experience but I would just like to assure you that this procedure regarding products is in place.

We of course will welcome a return or exchange should you take this option.


Sizing may have been incorrect.

I didnt try this on left too long to return but when I got home think the label may have been incorrect as didnt seem anywhere near the correct fit.

Wore it for running and skipping purpose

So I recently bought this sports bra from decathlon. I usually buy a size M in sports bras but after reading the reviews i bought an L and it fit me well. So if you want to go for it always buy 1 size larger Also the bra is really good, it supports very well while hight impact activities like running. The fabric used could have been a little better but comparing the prices it's good enough.

Additional Product Information


Main fabric

  • 53% Polyester cationic
  • 33% Polyamide
  • 14% Spandex

How is the maximum level of support of the basic running bra (level 5 on a scale from 1 to 5) guaranteed?

All our products are passed by our bust support test (measurement of the decrease in breast bounce when running) conducted in our laboratories. They are evaluated and given a rating from 1 (low support) to 5 (high support). Like all the KALENJI models, this sports crop top was given a level 5 rating and are suitable for all high-impact sports. *This sports crop top reduces bounce by 45% compared with a conventional bra when practicing high-impact sports.

What type of cup does the basic running bra have?

The running bra has 2 flexible single-thickness cups (no shell). We also offer sports crop tops and bras with breathable molded cups.

How was this basic bra designed?

This sports crop top has been designed for optimal comfort and breast protection: Like all the KALENJI models: * we don't use wires to avoid injury and compression of glands * we minimize seams around the nipple to avoid chafing * we choose fabrics that wick away perspiration to optimize comfort, but also avoid chafing.

A crop top or a bra?

The Basic running bra has sizes ranging from XS to XL, and is recommended for sizes up to a C-cup. The racer back, which is specific to the sports crop tops, spreads the support evenly across the back. For cup sizes from a D-cup upward, the RUNNING EASY ZIP BRA models or ADJUSTABLE RUNNING BRA WITH SHELL are more suitable.

Is this crop top suitable for younger girls?

Sizes 2XS and XS are suitable for emerging busts. This model is therefore particularly suitable for teenagers.

A score to compare the environmental impact of products

The environmental impact of the product is calculated across its entire lifecycle using a range of indicators. An overall score from A to E is calculated to help you more readily identify products with the best environmental performance by comparing the same type of product (T-shirts, pants, backpacks, etc.). Decathlon is committed to visually displaying environmental information. For more information visit:



Product testing

SUPPORT: the support was tested and approved by testers in the DECATHLON laboratory. Each size was tested separately. PERSPIRATION WICKING: the perspiration wicking test was conducted on each material in the laboratory to check that the fabric absorbs and transfers moisture from the inside of the fabric outward and eliminates it. WASHING: The washing and drying tests guarantee good stability (dimensional stability and colorfastness)
