About TheFluxion Chest Binder

1. What Are the Differences Between TheFluxion Chest Binder and Others?

At thefluxion, we understand that relying solely on increased pressure or harder fabrics to achieve a flat chest is neither healthy nor comfortable. That’s why we incorporate our expertise in developing compression products from the sports and medical industries into our product development process. By doing so, we ensure that thefluxion’s products not only provide a flatter appearance, but also offer safer pressure, a more intimate skin-like experience, and contribute to a safer and healthier body.

We are well aware that the volume of breast tissue is not compressible. Simply increasing pressure will not only fail to make the breasts smaller, but also from a health and safety perspective, our bodies should not endure excessive pressure for a long time, as this can lead to a range of health risks.

We change the shape of the breasts with appropriate pressure and combine it with ergonomic design to make the chest appear flatter. Our customers who participated in the internal testing affectionately referred to it as “visual magic.”

  • Step 1: Remove the bra or any compression clothing;

  • Step 2: Stand upright and measure the chest. Place the measuring tape around the fullest part of the breast tissue, typically at nipple level. Ensure that the tape measurement is snug. ( not too tight or too loose);

  • Step 3: Checking whether the measuring tape is in a horizontal line, especially checking the tap placed on the back of the body;

    Now you will get our chest measurement and check the following sizing chart to find proper chest binder size.

    If you need more details, please check the “sizing” page.

SizeBust size (in)Bust size (cm)

We offer a wide variety of binder sizes, from s to 8xl, from 76.2cm -137.0cm (see the pic above). If you are looking for a bigger size, please contact us, and we will customize it for you. We will continue to work towards covering more chest sizes if possible.

Depending on your workout strength level, light activities may be possible.

We do not recommend wearing a commercial binder if your workout is high-intensity, such as heavy weightlifting, hiit, or intense cardio exercise.

If your workout is light activity, and wearing a binder for your exercise makes you feel better, get one size larger than your standard thefluxion size.

Last but not least, during exercise, always pay attention to the signals your body gives you, such as whether your breathing is normal, whether your skin is itchy or painful, and whether you experience any unusual muscle pain in your chest or back. If you experience any discomfort, please stop using the chest binder during your exercise.

Yes, made of high-quality elastic materials, thefluxion is safe for water activities. But our binders are not dedicated as swimsuits, so we recommend the following:

  • Always wash it and dry it properly right after the water activity. Otherwise, the long-term moist environments may affect the product’s durability.
  • Allow your binder to dry off a little before taking it off. A wet binder could be more challenging to take off and more likely to cause skin irritation.
  • If you don’t feel well or have trouble taking deep breaths, stop swimming in your binder immediately.

Our quality binder materials can be machine washed and dried;

Hand washing with cold water and air drying can prolong the product’s lifespan to some extent;

Please air dry or wash the chest binder promptly after taking it off, as prolonged exposure to sweat may accelerate the aging of the product;

If not used for a long time, please store it in a dry and clean place.

  1. Preparation: Before putting on the chest binder, it’s important to prepare your body. Take a deep breath and relax your shoulders. Keeping your body dry can make it easier to put on and take off. It may be helpful to stand in front of a mirror for better visibility.
  2. Put your arms through the straps: Hold the chest binder in front of you with the straps facing upward. Slide your arms through the straps, similar to putting on a vest. Adjust the position of the binder so that it sits comfortably on your shoulders.
  3. Position the binder: With the binder on your shoulders, carefully pull it down over your chest. Make sure the binder is positioned evenly on both sides and covers the entire chest area.You can determine if your chest binder are worn correctly by observing if the markings on the hem are centered and symmetrical in the mirror.
  1. Adjusting the straps: After wearing the chest binder, make sure the straps are in the right position. The straps should not be too tight or too loose, they should be slightly tensioned and make you feel comfortable.
  2. Adjusting the position of the chest: Use your fingers to gently push the chest tissues to the sides, avoiding them from gathering in the middle of the bra. Make sure the chest is evenly distributed within the bra.
  3. Adaptation process: After wearing a binder, you may need some time to adjust to the new sensation. It is recommended to try different adjustments in front of a mirror to find the best adjustment for you.
  4. Listen to your body signals: Make sure the bra does not cause any pain or discomfort and ensure that you can breathe freely.
