Product Customer Reviews

Great running bra with no chaff issues. Strong hold once you get them on! I did find the sizing tricky. They are on the small side
very comfortable, medium support
Not as comfortable as expected. Can’t comment on moisture and chafing as will be returning without using for a workout
I usually wear a medium and purchased a large, which fits rather small. I like that it doesn't have padding which gets rearranged in the wash and you have to take it out and put it back in the correct position.
Hi Jewel,
Thank you for reviewing our Basic Running Bra.
We are glad that you enjoyed the absence of padding, it can definitely be a bother to slip them back in after the wash.
If you encounter any issues with the sizing, we will be more than happy to proceed to an exchange in store according to our exchange policy.
We hope to see you again soon!

Sizing is terrible…. Must be made overseas!!
Hi Diann,
Thank you for your feedback. We apologize for your experience with us. Decathlon is from France, our sizing is European. We always recommend to our customers that they wear the next size up or two from their usual fit. We would be happy to help you for your next visit in-store with finding the right size and fit for you.

Even moving to a larger size this bra was too small and tight.

I normally wear a medium in a sports bra but after seeing this in the store I knew by looking at it I would need a large. I’m 117 lbs and 5’3” bust size 34c. The large fits perfectly.
Hi Isobel,
Thank you so much for your review.
We are glad to hear that you were able to find the correct size & also that you liked our product.
See you soon :)

Price is right but it does provide proper support for running
Happy with the fit. Have since washed it and still fits well. Actually very good support for being quite basic in design. Price is definitely a plus!
Bought for my daughter and she loves it. It was a reasonably priced item unlike other stores.

How is the maximum level of support of the basic 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 crop top was given a level 5 rating and is suitable for all high-impact sports. *This running bra reduces bounce by 40% compared with a conventional bra when practicing high-impact sports.
What type of cup does the basic running bra have?
The running bra has 2 flexible single-thickness cups (no shell). We also offer sports crop tops and bras with breathable molded cups.
How was this basic bra designed?
This sports crop top was designed for optimal comfort and bust protection: As with all 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 crop top or a bra?
The Basic Running Bra has sizes ranging from 2XS to L, and is recommended for sizes up to a C-cup. The racer back, which is specific to the sports crop tops, spreads the support evenly across the back. For cup sizes from a D-cup upward, the Running Easy Zip Bra models or Adjustable Running Bra with Shell are more suitable.
Is this crop top suitable for younger girls?
Sizes 2XS and XS are suitable for emerging busts. This model is therefore particularly suitable for teenagers.

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)
