Hi WeyLee Oi,

Thank you for taking time to review our BASIC RUNNING SPORTS BRA BLACK. It is unfortunate that you had a bad experience with this product. 

However, do note that this product is a 'compressive bra' and for some, the compression may feel a little tight. We would advise you to consider a size bigger for comfort (We've opened another size up - XL for the latest collection) or explore our 'classic bra' options which is closer to the comfort of an 'everyday-wear' bra, yet providing the support needed for your runs. ( or

Should you require further assistance, do come down to any of our big stores and approach our Running Sports Advisors. we look forward to more of your reviews and sharing!

Yours Sincerely,
Lovely sports bra top

Great item and bargain!

Hi Amy,

Following feedback from our customers the brand has been made aware that this product does come up smaller than expected. As a result, they have designed a newer sized model that reflects our customer comments -

There is no padding.

The picture looked like its well padded but the item I got is not. How can this be used for running without pad support. Its also smaller than usual size.

Good bra but not high impact

It is a good bra to wear around house, it's very comfortable. But it can't be use for running, you must be kidding me with the description. It doesn't hold anything in place ;) But it would work for yoga, walking etc. You can't expect to buy a good running bra for RM 15.

Additional Product Information


Main fabric

  • 53% Polyester cationic
  • 33% Polyamide
  • 14% Spandex

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 are suitable for all high-impact sports. *This sports crop top reduces bounce by 45% 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 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 crop top or a bra?

The Basic running bra has sizes ranging from XS to XL, 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)
