About TheFluxion Chest Binder

At The Fluxion, we understand that relying solely on rigid fabrics or excessive constriction to achieve a flat look creates an uncomfortable experience. That’s why we incorporate our expertise in advanced textile engineering and high-performance activewear into our design process. By doing so, we ensure that The Fluxion’s products not only provide a smooth, flat silhouette, but also offer ergonomic support and a second-skin feel designed for all-day comfort.

We understand that effective binding isn’t just about compression. Simply increasing pressure can be restrictive and uncomfortable for daily wear. Instead, we utilize smart fabric technology combined with ergonomic design to redistribute mass and create a smooth, flat silhouette. By prioritizing fit over force, we achieve the look you want without compromising comfort. Our customers who participated in 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 when checking the tape placed on the back of the body. Now you will get our chest measurement and check the following sizing chart to find the proper chest binder size.

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 the intensity of your workout, light activities may be suitable.

We generally recommend standard activewear for high-intensity training, such as heavy weightlifting, HIIT, or intense cardio, to ensure maximum breathability.

However, if you prefer to wear our top for light activities to feel more confident, we suggest getting one size larger than your standard Fluxion size to allow for greater freedom of movement.

Last but not least, always prioritize your comfort. If you experience any restriction or discomfort during movement, we recommend stopping use during your workout.

Yes, made of high-quality elastic materials, the Fluxion is suitable for water activities. However, since our tops are not specifically designed as swimwear, we recommend the following:

Rinse and Dry: Always wash and dry it properly right after water activity. Long-term exposure to moisture may affect the fabric’s durability.

Removal: Allow your top to dry a little before removing it. A wet top can be more challenging to remove and may cause discomfort. Listen to your Comfort: If you feel restricted or uncomfortable at any point, we recommend stopping use while swimming.

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.

Getting Ready: Before putting it on, take a deep breath and relax your shoulders. Being dry makes it easier to slide the fabric on and off. Standing in front of a mirror can help you adjust the fit.

Step-by-Step:

1. Arms First: Hold the top in front of you with the straps facing upward. Slide your arms through the straps, similar to putting on a vest. Adjust it so it sits comfortably on your shoulders.

2. Positioning: Carefully pull it down over your chest. Ensure the fabric is positioned evenly on both sides and covers the chest area fully.

3. Check the Alignment: You can see if it’s worn correctly by checking if the hem markings are centered and symmetrical in the mirror.

Straps: Once on, ensure the straps are sitting correctly. They should feel secure but not digging in, providing a comfortable tension.

Smoothing the Silhouette: Use your hands to gently adjust and distribute the chest area evenly within the top. Gently shifting towards the sides helps create a smoother, flatter profile and prevents gathering in the center.

Getting Used to the Fit: If you are new to chest binders, you may need some time to get used to the snug sensation. We recommend trying different adjustments in front of a mirror to find what looks and feels best for you.

Comfort Check: Ensure the top feels snug yet comfortable. You should be able to move freely without feeling restricted. If it feels too tight, you may need a larger size.
