Why the 900 zip-up sports bra is ideal for high-impact activities
This 900 zip-up sports bra with superior support* is suitable for high-impact fitness activities (step, trampoline, treadmill running, etc.). It is easy to put on thanks to its adjustable straps, provides the perfect support without underwiring, and has thin, pre-shaped foam cups. The muscle back features technical, ventilated fabric for moisture management. *Reduces impacts by 45% 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 five 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. Refer to our size guide to find your corresponding sports bra size.
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).
Are products tested before being sold?
Of course! All our fabrics must successfully pass rigorous lab tests to ensure your comfort and safety. We test them for colourfastness, resistance to repeated washing, perspiration wicking and more - we call these our "torture tests". And after that? Is that it? No, there's more. We then have sports users put our products through the ringer. We listen to and analyse their feedback to fix what needs to be improved. And only then is your sports clothing ready!
And if you're not happy with the product?
You have 365 days to return your product to any DECATHLON store if it does not meet your expectations (although, maybe not straight after a workout...). You can also try out products for 7 days for free (by preauthorising your debit/credit card which will then be charged after 7 days) in order to be sure, when you make your purchase, you have the product you want!
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/

    Expected better.

    The quality is very good but I think there is a design flaw. The zipper is not flat, so when you wear a shirt, there is a tiny bump at the top of your chest which is very weird. The zipper ran down during my volleyball practice and luckily there is the hook that held it in place. Otherwise it would have been a real life nightmare. Would recommend their other sports bras but not this one.

    Zip-up, train hard!

    Personally, it is easier to put on & take off because of its design compared to other sports bras that I've tried. It fits well, very comfortable and provides good support during training.

    Best Sports Bra

    I am using this bra from past one month and it is one of the best bra i have ever used. It is very comfortable. Great Coverage, seamless, and padding contributes in great shape. I have used it for running, gym, volleyball and trekking. I have found it comfortable in all.
    The added advantage is that it is easy to put ON and OFF due to front zip opening unlike other sports bras. I request to please start making the same pattern bra in more prints. As of now only three prints are available and I have all 3.
