Ok quality

Quality was ok. Slightly stretched out of shape even though they’ve only been washed in a laundry bag. Good for the price.

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.

Too tight & constrictive. Had to return.

So comfortable

I've been struggling with chaffing from running bras and was trying to find one with seam free cups. I happened to spot this one in the sales and I've had no issues since especially on my long runs, no bleeding boobs which is fantastic. Just a shame they don't seem to stock it anymore or I'd have bought more

Sports bra

Sadly not a true size . I needed a 36C going by there measurement . I picked the size and it was way too small . Had to go up 2 sizes . Where as other decathlon brands have fitted.

Need More Sizes

I'm a 32DD/E. I always struggle to find sports bras that are supportive and fit properly. I really wish they did an S E-F. I have M E-F which is perfect around the cups but slightly too big elsewhere. I also have S C-D which is too small about cups... so frustrating!

Don’t waste your money

You won’t realise that this bra is useless until you use it. Don’t bother to purchase. I read the reviews and thought I would give it a try. It is really difficult to fasten and gives you about the same support as a regular bra. One for the gym DEFINITELY NOT RUNNING!! Very disappointed.

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)
