Crazy sizing

Bought online for daughter. Says EU medium UK 10. Collected brought home opened. EU medium is a UK 14. Never had a good experience of buying online with Decathlon.

Neck pain

I bought this bra for running. I wanted something slightly padded and for high impact. Unfortunately the way it is design pulls on the neck very uncomfortably. You are incredibly aware you are wearing it and it has given me pain.

Great improvement from previous model

Much better now it has the adjustment

Great but too small for cup beyond D

I am a 34 DD. I bought the size 12/14 L as recommended in their site. The lower band is too big and the bra itself is too tight and small to fit “the girls” comfortably. I manage to wrestle them in eventually, but I end up with overflow boobs on the sides. Not elegant! Conclusion, beautiful bras but if you have a cup size beyond say C or D you may want to try them on before buying, or go somewhere else. Shame. It is very hard to find good quality affordable sport bras for cup sizes D and beyond, yet, D is standard British cup size. Please Decathlon, can you cater for women with boobs? Not everyone has a boyish figure!

Running bra

Good size, comfortable and quite stylish.

The High-Support Fitness Sports Bra 900 is equipped with two preshaped foam pads.

A sports bra suitable for high-impact sports

The High-Support Fitness Sports Bra 900 is ideal for high-impact sports (HIIT, cardio circuits, jumping rope, treadmill running, body attack). The built-in foam pads enhance the natural shape of your chest and provide high support while exercising. The back features technical, ventilated fabric that wicks away perspiration. *Reduces impacts by 29.2% compared to a regular bra when doing high-impact activities.

A variety of adjustment options for a perfect fit

Every adjustment option on the sports bra improves your comfort. Hooks on the front help adjust the width of your bust, and you can bring the sports bra up or down on your traps with the sliders on the straps.

A sports must-have to protect your chest

While exercising, your breasts, which are fragile and supported almost exclusively by skin, experience much more stress than in everyday life. No matter your cup size or age, they are subject to movements and bouncing that can create a force of up to five times their weight. A sports bra provides the support and comfort you need while exercising. It protects your chest from impacts, pain, and premature sagging.

Picking the right support: not too weak, not too strong

Exercising can stretch the skin and ligaments in the chest. Without sufficient support, you may experience pain or premature sagging. But too much support can also be harmful over time: it must be perfectly suited to your cup size and the intensity of your effort. The aim is to protect your bust without altering natural breast movement.

Three different support levels for your sport

We designed our sports bras with three different support levels depending on your sport: low support for sports with gentle chest movements (Pilates, stretching, strength training); medium support for activities with moderate, non-repetitive bouncing (fitness dance, cardio training); high support for sports that involve intensive movement (step, treadmill running, trampolining).

Choosing the right sports bra size

If your sports bra fits well, you can be confident that it will support your chest and be comfortable. To pick the right size, take a tape measure and measure your chest circumference (without a bra): face 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; take the measurement without pulling it tight. refer to the corresponding table to find your size.

How are domyos bras designed?

Domyos sports bras are designed by our sports team to optimize your comfort and prevent health issues. We don't use underwires as they can cause injuries and compress lymph nodes, we minimize seams around the nipple to prevent irritation and we opt for components that wick away perspiration to keep you comfortable and make it much less likely your skin will become irritated.

How are domyos bras tested?

The models are verified in our labs using our bust support test (measures the decrease in the acceleration of breast movement during sports). They are then rated on a scale of 1 to 5: 1 for light support, 3 for medium support, and 5 for high support. *Domyos fitness sports bras guarantee to decrease the acceleration of breast movement by at least 10% (level 1) and up to 50% (level 5), in comparison to a regular bra.

Are decathlon products tested before being sold?

Of course! All our fabrics must successfully pass rigorous lab tests to ensure your satisfaction and safety. We check them for colorfastness, resistance to repeated washing, perspiration wicking, and more. We call these our "torture tests." And after that? Athletes like you test the products during their sports sessions. We listen to and analyze their feedback to fix what needs to be improved so that you can enjoy new outfits!

Determining the environmental impact of our products

A product's environmental impact is calculated for its entire lifecycle using various indicators. An overall rating (ABCDE) is given to help you easily identify products with the best environmental performance. We compare products of the same type to give each one a rating. Decathlon is a voluntary participant in this environmental labeling initiative. More information:
