Product Customer Reviews

Quality was ok. Slightly stretched out of shape even though they’ve only been washed in a laundry bag. Good for the price.
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.
cheap and good
Perfect fit, not too tight like other brands in this price range. Great support while running.
Hello Chetna,
Thank you for your review.
We are glad you are satisfied with your running bra.
Have a great day!

Comfortable a bit pricy durable quality my daughter is a happier basketball player. She’ll have to buy next time lol
Too tight & constrictive. Had to return.
Very impressed with this Bra .Soft and comfortable to wear All round workout is good in these. I think I need to invest in other colours
Does a better job than other more expensive bras.
Best bra I've bought, hope it's back in stick soon so I can get another one. Can finally do burpees comfortably again!
Brilliant. Even when running, you get firm support.
Fantastic bra, really comfortable, supportive, and doesn't leave you soaked after a workout, adjustable and really pleased with it. - second one i have purchased.
I bought this bra for running and it’s perfect. I’m a size 34C so my boobs do bounce when I run and it minimises it than my other sports bras. highly recommend :)
I bought this product first in Ghana @ the Decathlon store @ Junction mall in 2018. the bra served me really well. it is firm, good for running and other high intensity workout.. I use a Size 38 DD cup, so you can understand how heavy I am. I strongly recommend it for heavy ladies like me..
Why do I always find decathlon stuff so difficult to fit, the sizes are nothing like any others and as the changing rooms are closed you end up having to return stuff which when you're not local is very annoying
Not good fit

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)
