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 moulded 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 impacts 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, protecting your chest from impacts.
Three 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 towards 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 minimise 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 categorised: 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 life cycle 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, bottoms, backpacks etc.). Decathlon openly displays the environmental ratings of its products. Find out more: http://sustainability.decathlon.com/

    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
