comfortable and not too restrictive bra. pretty color, pleasant material that wicks away perspiration well. I recommend it for "small chests" because the support remains flexible, or for sports with little impact.

simple and efficient

Be careful about size

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.

A score to compare the environmental impact of products

The environmental impact of the product is calculated across its entire lifecycle using a range of indicators. An overall score from A to E is calculated to help you more readily identify products with the best environmental performance by comparing the same type of product (T-shirts, pants, backpacks, etc.). Decathlon is committed to visually displaying environmental information. For more information visit:



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)
