Not suitable for high impact use

Very comfortable bra, but definitely not suitable for high impact! As soon as you start exercising, the bounce is very evident, and even becomes painful!

High Impact - No way !

As I was so impressed with your deep cup high impact bra, I thought I would try this one. What a waste. As soon as I opened it , I could feel it was a lot flimsier than the deep cup . It supposed to be for larger breasts ( 3XL) and for high impact . Well its not. As soon as you jump or move, you can feel the bounce. Certainly not fit for cardio. Im going to use mine for walking .

Very difficult to know what size to order. You don't use the ordinary British bra sizes. This was my second attempt!

Great for some.

Hi.i really liked this sports bra,but actually got it as i suffer with rheumatiod athritis in all my bones.even chest bone pain and ribs. it was easy to do up,for able bodied people,bit harder for me. The only thing i found really wrong was that for me the straps cut into my shoulders a bit. I am large busted,so need support.but for someone able bodied i am sure it would be excellent. Well done. Thank you. Kim.

Sports bra

Very good support, excellent fit, does feel uncomfortable around shoulder/neck after a few hours maybe would benefit from a bit of padding in that area, this is possibly due to the bra being a bigger size

Not for tall women

Not suitable for tall women as no adjustment in straps possible- not enough strength in band under bust as it rises up when you raise your arms. Had to send it back. Straps seemed comfortable and design is nice though.

Superb Fitting

Very supportive bra, full coverage and very good bounce control. Only con is, padding is very light.

Super awesome

This gives awesome support. I did wrestling, weightlifting.

Best Possible

Plz get this back!

High Support And Comfortable

Great support

Good Buy

I use it everyday for gym. Dries super quick so easy to wash. It's a comfortable wear. Minus one star because I expected the zip to open completely which it doesn't.

Why the power bra is ideal for high-impact activities

This Power sports bra with superior support* is suitable for medium- to high-impact fitness activities (step, trampoline, treadmill running, etc.). The full-fitting cups will keep you feeling confident. Specially designed for large bust sizes, non-wired design with molded cups. The muscle back features technical, ventilated fabric for moisture management. *Reduces impacts by 36% compared to a regular bra when doing high-impact activities

A sports must-have:

When working out, your breasts are put through more stress and impacts than during your daily activities. Your breasts are subject to movements and bouncing that can create a force of up to 5 times their actual weight. 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. You can then check this measurement against the size chart.

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).

A rating to compare the environmental impact of products

A product's environmental impact is calculated for its entire lifecycle using various indicators. An overall rating (ABCDE) is given, allowing you to easily identify products with the best environmental performance by comparing similar products to each other (T-shirts, pants, backpacks etc.). Decathlon openly displays the environmental ratings of its products. Find out more:
