Kalenji running bra

Was bit unsure when i bought it online but turned out to be a good fit and comfortable bra. Solves the purpose as while running you need something that fits well and is coomfrotable. Would highly recommend.

Gave me a massive gash on my breast!

I used the sizing system the website recommended. On the second wear I had a large gash on my breast from where it had dug in, got infected and caused me a lot of pain. DO NOT BUY THIS ITEM

Keeps them where they should be

I used to buy a very well known make ....but having used these for over 2years and run for miles I’m converted

Good support

Good support bra with adjustable straps and hook and eye fastening at back. Good for comfort when running - my only negative is the positioning of the tag under one arm isn’t ideal for rubbing.

I now have two - well worth the money

I love this bra. I now have two and have no reason to change. I’m a 34C size 10, and I feel well supported in this range.

Good support sport bra

I bought this sport bra for running and working out and I'm very pleased with it. It has a good support and is easy to put on and off.

Very uncomfortable and little adjustability

I purchased this bra after trying them on in a Decathlon store. They fitted fine (size L) so I purchased 2. However after wearing the bra for more than 30 minutes I noticed that the shoulder straps are extremely tight and uncomfortable on my neck and shoulders leading to upper back pain. There isn’t much adjustability in the shoulder straps so they are useless now.

The most uncomfortable bra I've ever tried on

Despite the excellent reviews from other users, I found this to be a very strange fit. I initially ordered the medium, but it was a bit too tight. I exchanged it for a large, and bizarrely, it was even less comfortable - the straps really pinched and dug in. There's very little adjustment, and I just couldn't make it fit. Shame, because as sports bras go it's nicely styled.

Great sports bra

I was over the moon to find this bra. Great price, great support, comfy and looks good. Couldn't ask for anything more. So happy I've ordered another one in one of the other lovely colours.


Thrilled to bits,the most comfortable and easiest to get on sports bra that I've ever bought, so much so I'm going to order another one ! It's being washed after every wear and the support and fit is still the same as the first time I wore it, I would highly recommend.

As a 34E, I find the racerback style of this feels very heavy on the trapezius muscle. It is less supportive than my specialist sports bra but sufficient. It restricts deep breathing by a small amount which is annoying on a run. The inner cup is like neoprene, awful plastic smell and horribly sweaty. It is functional and OK given my current budget but I'd hoped for better.


This is the easiest to get on and most comfortable sports bra that I've ever bought and by far the cheapest. Would no doubt recommend

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 racerback, 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)
