Running bra

I must not have read the product description because if I had I would have not bought this bra. There is no padding in the cup area nor does it support well. I feel it’s somewhat see through.

Great for every day use

Super comfortable and good support. Would recommend.

Great value bra

My usual size fits perfectly. Good quality fabric, washes well. I’ll probably buy in more colours.

Good fit and great value

I've tried a few running bras and this is the best - and least expensive - one I've found. So much so that I bought a second, and came back today to try buying a third. Sadly they've run out in my size, so I'm leaving a review instead! It's a good bra and the material means it's not too heavy or sweat-inducing. Having the hook and rings to turn it into a sort of racer back gives more support and still feels comfortable, though it's a bit tricky to do up the hook until you've had a bit of practice. Top tip - make sure the hook is pointing the right way before you put the bra on! I definitely recommend this bra and *really* want to get another one when I can!

Great supportive running bra

This is the third bra I’ve brought. They are soft supportive and very comfortable. I love the extra hook on the back that allows you to turn it into a racing-style back & provides additional support

Additional Product Information


Back fabric

  • 76% Polyamide
  • 24% Spandex

Main fabric

  • 68% Polyester cationic
  • 32% Polyamide


  • 100% Polyamide

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 flexible single-thickness cups (no shell). The cup material, which is durable and fine, allows the bra to dry quickly. We also offer sports crop tops and bras with breathable molded cups.

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 (risk of injury or of compressing the glands) * we keep the number of seams around the nipples to a minimum (risk of irritation) * we use components that wick away perspiration (this criterion improves 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. We read your reviews of the previous version of this product and improved the hook: once attached, it will remain in place thanks to the safety catch.

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 given to help you easily identify the more eco-friendly products by comparing products of that same type (T-shirts, pants, backpacks, etc.) Decathlon is committed to displaying the environmental information of its products.

And what if the back length is too small?

If the cups fit but the chest strap is too tight, you can extend its length using the KALENJI BACK EXTENDER that is available in 2 heights: 38 mm: is compatible with all the A cups and B cups except sizes 38B, 32C, 34C and 32D. 57 mm: is compatible with sizes 38B, 36C, 38C, 34D, 36D, 38D and all the E cups.



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)

Care instructions

machine wash maximum 30°, preferably with liquid detergent and in a laundry bag. Wash only with similar dark colours. Do not tumble dry. Do not iron.
