Hi Amy,

Following feedback from our customers the brand has been made aware that this product does come up smaller than expected. As a result, they have designed a newer sized model that reflects our customer comments -


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.

Shape and size

Quality seemed ok but fit was not for me.

Very small

Very small seems its support comes from squeezing you flat

Hi Colleen,

Thank you for taking your time to review this product. It is true that this product provides support using compression, of course this is not ideal for all. We do however have bras in our range that provide a more traditional style of support through the use of cups and straps. As you are not satisfied with this product, please return for a full refund.

Sports bra

Its very tight coz of material used.

icon-circle-checkmark Verified purchase

Having read the previous reviews and seeing this product came up small, I ordered a medium and a large. Now, I have no boobs to speak of (34B) and even the large was incredibly tight and dug in around my back. I'm quite small framed (size 10 in tops normally), so it seems absurd that I would have to order an XL for a comfortable fit, but then might lose the support element. Sending both sizes back, which is disappointing as it looks really nice until you try to squeeze into it!

Hi Kerry,

Thank you for taking your time to report a sizing issue with this product. We have received a large amount of feedback on the sizing being too small. As a result, I am pleased to say that as of 2020 this product will be available in a new sizing to correct the issue.


Great for smaller ladies

I’m a size 8 with A/B cup, and bought the small (without trying on) It is tight but stays put and doesn’t ride up! It’s been washed a few times and seems fine. Excellent value.

Comes up very small

Looks like it would be a great value purchase but comes up way too small. I think you would need to buy at least 2 sizes bigger than normal

Not as high impact as I'd hoped

But the colour is AMAZING

Normally need size M, bought size L still too small have to bring it back. Not nice!

Hello Stella, 

Thank you for taking your time to write this review. This product relies on compression to offer support. Unfortunately this type of support isn't suitable for all and will be too small for some of our users. Please return to the store for a full refund if you haven't done so already.

As an alternative, within our running underwear range we also offer a more traditional style of support through the use of cups and straps. These generally are better for those requiring a larger size.


I'm a very petite women, bust size b cup and bought a size small. I couldn't even get it past my chest let alone over my breasts. You need to look at your sizing as it's tiny as it's more of a child size. Very disappointed

Hello Beckie, 

Thank you for taking your time to write this review. Your review along with others will be taken into consideration when designing future products. So far 58% of our reviews have suggested that this product is sized small to moderately small.

Please return for a full refund if you haven't done so already.

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 bra reduces bounce by 45% compared with a conventional bra when practising high-impact sports.

What type of cup does the basic running bra have?

The running bra has two flexible single-thickness cups (no shell).We also offer sports crop tops and bras with breathable moulded 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 minimise seams around the nipple to avoid chafing* we choose fabrics which wick away perspiration, to optimise 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 upwards, the RUNNING EASY ZIP BRA models or ADJUSTABLE RUNNING BRA WITH SHELL are more suitable.

Is this crop top suitable for younger girls?

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