Great bra

Comfortable, supportive also on high intensity workouts and it look great. I am very happy with this bra!


Having a larger bust I’m needing the support when running. I do feel supported in this and I don’t feel it digs in like a lot of other sports bras do. I like how it has the padded cups so still keeps the shape rather than flattens.

Not suitable for treadmill workout

Nice bra too comfy fit, ok for low/medium impact workout. Definitely not suited to running as I hoped when purchasing it. Far too much bounce and wobble on treadmill and Vario.

Not supportive

Advertised as supportive for high intensity. Also bought low intensity bras from decathalon and just as supportive. Had much better for cheaper!

Thanks to leave your opinion on  900 Women's Cardio Fitness Sports Bra . I'm sorry to hear about your bad experience, I ll will forward your feedback to our product manager in order to investigate your issue in terms of support. The 900 bra collection has to be really supportive for HIIT workout.
Don t forget you can claim a total refund or a product change in your nearest Decathlon store
Kind regards

Decent sports bra for a good price

I’m a 38DD and struggle to find decent sports bras for high impact activities; tend to go for shock absorber but at double the price of this from decathlon, it can be costly. I bought the blue / coral version as I liked the style of it and I’ve been very impressed with the quality. I’m also able to remove it after a work out without too much effort (it’s a pull-on/off rather than having a fastener)

Genuinely surprised by this

Wore it to bootcamp (so running and bouncing as well as weighted exercises) hoping for a reasonable level of support but not holding my breath. Pleasantly surprised by comfort, support and lack of bounce! I’m a 30D so this was great seeing as this bra is good value.

Visible seam

I didn't like the seam being visible through a sports top so I returned this. But construction seemed good and comfortable. The mesh panel between the cups was cooling.


Good for running.

Loved the product

I've been using it for just over a year and it still gives good support.

Ammmmazing Sports Bra! One Of My FIRST BEST!

Best one for Jumping Jacks, Spot jogging, High Knees workout!


Extremely supportive

Why the 900 sports bra is ideal for high-impact activities

This 900 sports bra with superior support* is suitable for high-impact fitness activities (step, trampoline, treadmill running, etc.). The push-up cups provide maximum support and a flattering look. The muscle back features technical, ventilated fabric for moisture management. *Reduces impacts by 52% compared to a regular bra when doing high-impact activities

A sports must-have:

When working out, your bust is put through more stress and impact than during your daily activities. The movements and bouncing mean that breasts can move with a force up to 5 times their initial weight, depending on intensity. Wearing a sports bra provides both the support and comfort you need when doing a physical activity.

Protect your breasts:

No matter your cup size or age, your breasts suffer a lot of impact during exercise. As fragile organs supported almost exclusively by your skin, they need specialist support. If you just wear a normal bra with less support, it could lead to pain and, over time, to sagging. A sports bra is just as important as your other sports clothes and shoes in protecting your body from impact.

3 levels of support depending on your sport:

- Low support (yoga, stretching, muscle strengthening, etc.) for activities where the breasts will not move much. - Medium support (fitness dancing, cardio training, etc.) for moderate, non-repeated bouncing. - High support (step, running, trampolining, etc.) for activities involving intensive movements.

Choosing the right size

The right size ensures good support and a comfortable fit. To figure out your bra size, take your bust measurement: * Measure yourself without a bra on. * Use a mirror. * Hold your tape measure horizontally at the top of your back toward the bottom of your shoulder blades. * Bring the tape measure across the fullest part of your bust. Without pulling it tight, take the measurement.

How are domyos bras designed?

Our models are designed to increase comfort and help prevent health problems: * we do not use underwiring (risk of injury and compression of the lymph nodes) * we minimize seams near the nipple (to prevent chafing) * we use components that wick perspiration away from the body (improves the level of comfort and considerably lowers the risk of chafing).

How are domyos bras tested?

All our models are verified in our labs using our bust support test (measures the decrease in acceleration of the breasts during sports). They are rated and categorized: 1 : light support 3: medium support 5: superior support * Our fitness bras guarantee a reduction in the acceleration of the bust compared with a standard bra. 10% minimum (level 1) up to over 50% (level 5).
