Comfort Running Bra,peach

Best sports bra I've ever bought

I'm so happy with this sports bra! It's lightweight, comfortable, stays really dry and stops annoying bouncing. The support is excellent. Nipples don't show through, and it doesn't make my chest look flattened or enlarged. Even better, it doesn't smell awful after one use even like some fabrics do if you sweat a lot when you exercise. I'll definitely be buying another for when this one is in the wash.

product is awesome

I do not have any issues with the product, but there were two aspects I though it could be better.. One is the front stitch, it is visible on all my t-shirts and is very prominent, and secondly the colour, it is extremely boring. skin colour and black are as if the defining colours. I insist on having a more fun, vibrant like neon colous when it come to sports..

Pls don't buy it. It's okay for walking but not for running . It's an average product. Pls bring a good running bra.

Hello Ms. Priya,

I hope you and your family are keeping yourself safe and sound. I am extremely sorry for the inconvenience caused to you because of the comfort running bra. 

I totally understand your concern but in order to help you with the solution, I want to understand the issue that you face while running as this product is specifically made to provide support while practicing hight impact sports and reduces bounce by almost 44%. However, once the stores are open you can then visit your nearest store and can consult with our running sales advisor. They can guide you with and can help you with the best possible solution available. 

In case of any other concerns, please let me know. I'll be happy to assist you. 

Very comfortable!

I've worn different sports bras just to make my shoulders as comfortable as possible due to the demands of my job. While others that I bought from the high street are decent, they tend to be on the slightly expensive side while the cheaper ones I bought before tend to eventually dig into my shoulders. Then I decided to look into Decathlon and found this. When I first used it, it was very comfortable and offered the support without any wires underneath and it didn't put any pressure on my shoulders. I would definitely buy this again.

Used it more than for running

This has great support indeed. Used it for cardio boxfit and crossfit all together and give me such confidence.

I Want Same Sports Bra

Good quality


I’m a 34DD & I’d been struggling to find a sports bra that gave strong support without having to pay a huge price tag or that caused itching with a rash after 2 minutes of running. I had tried many bras & not one worked until I finally found this bra! After buying this bra 3 days I’ve been running every day & can say it is genuinely the most comfortable sports bra I’ve ever worn. It offers excellent support as well as wicks away sweat so no itching where the bra sits under the chest area Highly highly recommended!

Kalenji sports bra

The design, fit & color are nice but after the 3rd use/washed within 2 weeks after buying the item, all the linings of the the mesh portion detached. The sports bra now look stringy. Afraid a run Will further destroy the undergarment on its next use/wash (Even if its protected by a laundry net) & I wont be able to use it again. A bit disappointed on the durability/quality of the item. ☹️. How do we remedy the problem?

How is the maximum level of support (level 5 on a scale from 1 to 5) of the comfort sports bra 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 crop top reduces bounce by 44% compared with a conventional bra when practicing high-impact sports.

What type of cups does the running bra have?

The comfort running bra has 2 flexible molded cups. Breathable with mesh fabric under the chest and between the breasts. We also propose sports crop tops and bras without firm cups.

How was this running 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 sports crop top or bra?

This adjustable sports bra with cups was developed to combine the advantages of a sports bra and a crop top: - the racer back, which is specific to a sports crop top, spreads the support evenly across the back - the adjustment systems (back and straps) can be used to adjust its size, like a conventional bra. The back opening makes it easy to pull on over the head.

Choosing the right size for this comfort bra

We developed this running bra with several cup sizes. Each "standard" crop top size (S, M, L, XL, etc.), which corresponds to your T-shirt size, is available in several cup sizes. For example: M cups A/B and M cups C/D. This type of fit, combined with elasticated materials, offers enveloping, rather than restrictive, support. A 3-position back fastener and adjustable straps for a snug fit.



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)
