Product Customer Reviews

Good for high impact and comfortable. However the zip occasionally slides down, which is VERY annoying while you are in the middle of a workout. Also, the zip is too "bulky" and very visible behind a shirt, it should be flatter and not as noticeable.
Very comfortable & great value for money. Very happy.
When I'm wearing it, I feel that it is might be a little tight, but as soon as I start to run, it's very comfy and it completely supports my boobs.
I am so impressed with my new sports bra!!! The feel, fit & size are amazing. The quality has been great so far too.
Will have to return this product - it was much smaller than expected and I didn't manage to close the zip. Taking it off was also quite difficult.
These give excellent support and are extremely comfortable.
Great support
I tried this on and found the straps cut in around my front armpits so it went back in the packet. I'm an 8-10 and ordered size Small. The rest of the fit was OK.
I purchased this for my wife as her old bras weren't up to the job. It had to be suitable for high intensity sports (running) and also provide extra support as she is still breastfeeding our little one. It is really comfy and does the job perfectly. The size guide is also spot on.
Great bra, amazing support for running when you have a generous breast... But the straps gave me terrible allergy (I bought 2 of them), first time I have this kind of reaction with a sport's bra!
I really liked the idea of this bra. The band around the bottom is the perfect size on me however it took my husband and I a combined effort to get this thing shut over my chest. I immediately wanted it back off since I was spilling out everywhere including the armpits. A larger size would be too big around the bottom. I wouldn't recommend this for anyone larger than a B/C cup
Great bra, fits perfectly. The sizing is accurate.
Great quality product
No jiggle total support great quality. Will be buying more
super supportive for bigger boobs and it's so nice having the zip at the front because it's pretty and it means after a workout you don't need to try pull it over your head. Some of the reviews say that people have experienced rubbing at the bottom of the cleavage and I didn't have that at all. Could be a little more supportive but even for high impact and running it's great and doesn't hurt or feel the pull or anything.

Why is the 900 zip-up sports bra 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 the front zipper and adjustable straps, provides the perfect support without underwiring, and has thin, preshaped 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 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. 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 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).
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 colorfastness, 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 analyze their feedback to fix what needs to be improved. Only then is your sports clothing ready!
What if i'm not satisfied with my 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 preauthorizing 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
