Product Customer Reviews

Very comfortable, great support, very good value!
Too small and lining was lumpy
Hi Emily,
We are very sorry to hear about your experience with the classic running sports bra. As our sizing is European, the sizes do fit small. We invite you to return the bra and come try on some different models and hope you will find one suitable.

I really like this bra
I used to only wear bralettes and sports bras but once i found these it was amazing. I got myself another one because i love them.
It dose what it says on the tin
Not as supportive as I was hoping for when running. OK for gym workout.
Hello Melanie,
We are sorry to hear that the bra didn't meet your expectations. You are welcome to bring it back in the store and exchange it for a different model that suit you better.
Thank you for taking time to review our product.

Bought as a addition to a much loved running bra for a discontinued KALENJI SPORTANCE RUNNING SPORTS BRA - BLACK References : 850409, I discovered, much to my frustration, when trying on at home there’s an oblong loop on the back of each shoulder strap which refused to stay the right way round. My old kalenji bra has no loops at all… Please do away with these loops.
So comfortable and supportive. I have a couple of these and use them for cycling, not sure how they would be for higher impact sports. The mesh panel at front keeps you cool. Such value for money compared to other stores similar products. Wash well too.
Very comfy and reliable bra
Great bra very comfortable, just check your measurements to make sure you get the correct size
Wears well.
Comfortable, no rough edges, supportive, breathable.
I love this bra. Fits perfectly, supports during running yet comfortable enough for every day use.
Tight but not supportive enough for a running bra
Super comfy

How is the maximum level of support of the classic 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 bra was given a level 5 rating and is suitable for all HIGH IMPACT sports. *This sports bra reduces bounce by 37% compared with a conventional bra when practicing HIGH IMPACT sports.
What type of cups does the classic running bra have?
The Classic sports bra has 2 fine, flexible foam cups offering optimal comfort. This foam also conceals nipple protrusion.
How was this classic bra designed?
We designed a sports bra for optimum comfort and breast protection: As with all KALENJI models: * We do not use underwiring (due to risk of injury or of compressing the glands) * We keep the number of seams around the nipples to a minimum (due to risk of irritation) * We use components that wick away perspiration (to improve comfort while also considerably diminishing the risk of irritation).
Straight or crossed straps?
The straps of the Classic running bra may be worn vertically, like a conventional bra. They may also be attached in the middle of the back, using a hook that connects the 2 rings. This frees up the shoulders and gives greater freedom of movement. The crossed straps also ensure better bust support. A reinforcing foam was added at the straps for even more comfort.
What if it is too tight across the back?
If the cups fit but the back strap is too tight, you can extend its length using the KALENJI BACK EXTENDER with reference: 8584752 (black) and 8584753 (white). Each pack contains the height of the back extension that fits each size: 1.5" (38 mm): compatible with sizes XS AB, S AB, S CD, M AB, M CD, M EF, L AB, and L CD. 1.75" (45 mm): compatible with sizes L EF, XL CD, XL EF, 2XL EF, and 3XL EF.
How to put your bra on
For easy dressing, we recommend clasping your bra at the front and then sliding it back so that the clasps are at the back. Pull the bra up to your chest by slipping the straps on as you would for a conventional bra.
A score to compare the environmental impact of products

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)
