With this medium-support sports bra, you can give your all in moderate-impact activities, such as dancing, working out, cardio training, cycling, etc. while having optimal chest protection.

What activities is the medium-support muscle back seamless bra suitable for?

When playing, it’s essential you feel comfortable when moving. This means that you should choose clothing that makes it easier to move and take up postures. 
This sports bra has been designed with this in mind. We design a muscle back that will free up your shoulder blades so you have move freedom of movement for your arms.

How does the medium-support muscle back seamless bra provide freedom of movement?

You go all out, to the point where you are often fully covered in sweat at the end of a session. This isn’t always a very pleasant feeling, right? Well, thanks to this sports bra, you can say goodbye to moisture caused by sweat. The technical fabric can wick away sweat. It also dries faster to keep you dry. 
For greater efficiency, we also added a ventilated area between the breasts.

Stay dry, even when you are pushing yourself to the limit! How is this possible with the seamless, muscle-back, medium-support bra?

The running bra has two flexible single-thickness cups (no shell).

What type of cups does this medium-support muscle back seamless bra have?

Did you know that your breasts are supported almost exclusively by your skin? This makes them vulnerable and, during physical activies, the forces exerted on them are even higher than usual. The movements and bouncing they experience can make them up to five times heavier depending on the intensity of the sport. Wearing a sports bra will give you all the support, comfort, and protection you need. You are also protecting them from impacts, pain and premature sagging.

Why must your chest be supported during sport?

During sports, breasts experience forces that stretch the skin and ligaments of the chest. Lack of proper support can cause pain and premature sagging. However, too much support can also have negative consequences. The level of support your bra provides must be tailored to your bust size and the intensity of the impacts. 
The objective:To protect your chest while preserving the natural movement of the breasts.

What are the advantages of choosing between high, medium or low support?

Our labs test the models using a bust support test that measures the reduction in breast movement acceleration during sports activities. They are evaluated and then sorted into the following three levels: 1 for low support, 3 for medium support and 5 for high support.

How are the support levels of the Decathlon sports bras tested?

Depending on the type of sport you do, the support level of your bra will vary. We offer the following three options:
- Level 1: low support for activities that require slight chest movements (pilates, stretching, muscle strengthening, etc.); 
- Level 3: medium support for activities that cause moderate bouncing (dance, fitness, cardio-training, etc.); 
- Level 5: high support for activities that involve intense movements (step, treadmill, trampoline, etc.).

What sport should you associate with what level of support?

To keep your bust supported and comfortable, the bra size that you choose must be suit your body shape. This is how you do it:
- Stand opposite a mirror with a tape measure;
- Place it horizontally at the top of your back, on the lower part of your shoulder blades;
- Hold the tape over the largest part of the bust;
- Read the measurement without pulling the tape measure tight;
For greater accuracy, use our online calculator.

How do I measure the size of my bust to choose the right sports bra?

The sports bra comes in sizes ranging from XS to XL and is recommended for cup sizes up to a C cup.
The racer back spreads support evenly across the back. 
For D-cup and above, we have developed other, more suitable models.

What size of medium-support muscle back seamless bra should you choose?

Decathlon sports bras are designed to maximize comfort and prevent health problems. There reason there’s no underwire is to eliminate risks of injury and compression of the lymph nodes. The minimal seams at the nipple reduce irritation risks. By focusing on sweat-wicking fabrics, we can guarantee your comfort while significantly reducing the risk of skin irritation.

How are Decathlon sport bras designed?

Designed for intensive sports use, this bra can be washed and rewashed. Do not wash at temperature over 30 °C (86 F) and put it in our washing bag, which is sold separately (item ref. 8505236). Do not dry in a dryer.

What activities can you do with the moderate-support zippered ribbed sports bra?

Whatever the activity or its intensity, it's important to feel comfortable and at ease with your movements if you're going to enjoy it. And to give yourself the best chance of success, our first piece of advice is to choose the right outfit. This sports bra does just that. By adding elastane, we've increased its stretch. The muscle back also frees up the shoulder blades for even greater ease of movement.

What is it about the moderate-support zippered ribbed sports bra that gives you so much freedom of movement?

Sweating and staying dry may seem paradoxical, even idealistic. But we've risen to the challenge by using perspiration-wicking fabric in the design of this sports bra. Now you can give it your all without fear of ending up soaked at the end of the session.

How can you stay dry even when you're exerting yourself wearing the moderate-support zipped ribbed sports bra?

For a sports bra that's easy to put on and take off, we've included a front zipper. It is self-locking to prevent it from opening during use. Simply zip up and press the slider to lock the zipper.

Why is the moderate-support zippered ribbed sports bra so easy to put on and take off?

You may not be aware of it, but your breasts are supported almost entirely by the skin, which makes them more fragile. During sport, they are put under much greater strain than usual. Regardless of your cup size or age, breast movement during a workout can exert a force up to five times your breasts’ actual weight. Wearing a sports bra gives them support, comfort, and protection. It protects your chest from impacts and pain.

Is it really important to protect your breasts during sport?

Sport puts stress on the breasts, stretching the skin and ligaments. The absence of support increases the risk of pain or premature sagging. But too much support can also cause long-term damage. It is therefore essential to adapt the level of support in your bra to your cup size and the intensity of the impact you experience. The aim is to protect your bust without altering natural breast movement.

Why is it important to choose the right support?

Prototypes are approved in our laboratories using a test to assess breast support. This test measures the reduction in the acceleration of breast movements during sport. They are assessed and then classified according to 3 levels: 1 for light support, 3 for medium support, and 5 for high support.

What tests have been carried out to validate the support levels of Decathlon sports bras?

Depending on your sport, you will not choose the same level of support. You can choose between 3 levels:
- Level 1: light support if the activity involves gentle chest movements (Pilates, stretching, muscle strengthening, etc.); 
- Level 3: moderate support if the activity causes moderate bounce (dance, fitness, cardio-training...); 
- Level 5: strong support if the activity is associated with intense movement (step, treadmill, trampoline, etc.).

What level of support should you choose for your sport?

If the sports bra fits well, it will support your chest and be comfortable. To make the right choice:
- In front of a mirror, use a tape measure;
- Place it horizontally at the top of your back, on the lower part of the shoulder blades;
- Bring the tape measure across the fullest part of your bust.
- Measure without pulling the tape measure tight.

How do you know what size sports bra you need?

Decathlon's sports bras are designed by our sports team to optimize your comfort and prevent health issues. The absence of underwiring removes the risk of injury and of compressing the lymph nodes. By getting rid of seams over the nipples, we reduce the risk of chafing. And by prioritizing perspiration-wicking fabrics, we ensure your comfort while considerably reducing the risk of skin irritation.
