"this is my first time ever getting a binder and it’s really awesome! it fit’s really nice and still gives the effect, it does go looser under so if i wasn’t wearing a shirt it would show my chest more but overall it’s really great and it arrived super fast! i’ll definitely be buying from here in the future :)"

"I just got this binder and really like it! It’s my first binder and I got a large, so definitely go to the bigger size if you’re in between two! I’ve included a before and after picture to show the difference."
What You’ll Need:
- A soft measuring tape
- A mirror (optional, to check the tape’s position)
Step 1: Stand naturally and relax your shoulders.
Step 2: Wrap the measuring tape around the fullest part of your chest (usually over the nipples).
For example:

Step 3: Make sure the tape is snug but not too tight—avoid compressing the tissue.
Step 4: Keep the tape parallel to the floor and check in a mirror if needed.
Step 5: Record the measurement in inches or centimeters.
To find the right size, check the size chart (at the top of the page) and compare it with your chest measurements. A well-fitting binder should be snug but never restrict breathing or cause discomfort. If you’re between sizes, size up for safety and comfort.

Hand wash
1. Use warm or cold water.
2. Lather the binder with a mild dish soap or laundry detergent, and gently wash it through.
3. After washing, gently squeeze the binder to remove excess water before air drying it.
4. Make sure to rinse the binder thoroughly to ensure all soap is removed before drying.
Machine wash
- Machine wash on the delicate or gentle cycle with cold water.
- Use a laundry bag to protect your binder from wear and tear.
Air dry
Just hang it up or lay it flat overnight, and it should be dry and ready to use by morning.
Machine dry
We advise against machine drying as exposing the binder to very high temperatures can cause it to shrink.
If you must use a dryer on occasion:
- Place the binder in a delicates bag for extra protection.
- Set the dryer to the lowest heat setting.
- Limit the drying time to 10-15 minutes.
- After the initial drying time, air dry the binder for the remainder of the drying process.
Using the dryer only when necessary and following these steps will help maintain the binder's quality.
If you have any questions, please don't hesitate to contact us!
It’s really important that you always wear your binder in the correct size.
If you’re starting out with binders we recommend building up the time that you wear. For example, start with 2 hours, the next day 3 hours, and so on. Build this up to a maximum of 8 hours per day.
It's also important to remember to never sleep in a binder as these are compression garments. We also never recommend double-binding/wearing two compression garments at the same time layered on top of each other.
If you experience any pain/discomfort while binding, stop binding.

Flat chest who!!
Y. P. 5/5
This is my first binder but I’ve had lots of sports bras in the past, I can definitely recommend this product. Really great build quality, the sizing is perfect, compression is impressive. Make sure to use a tape measure to get the sizing right before buying. I turned out to be an XL and it fits great, wouldn’t go any smaller. Might end up buying the 3.0 just to see if there’s much difference cuz idk how it could get much better. Super happy with the product 👍

I have recently discovered my genderfluid identity and couldn't be happier when I found this site. The binders are affordable and comfortable, so when I have my masc days, I can fully embrace the confident and sexy king I am. I cannot thank you guys enough!
M. M. 5/5
Great binder! It was a little tight on the first day, now i do not feel it at all. I usually wear S, but I ordered Medium, fits perfectly. It is easy to take off and put on. Binds really well
S. 5/5 Verified
Very professional company. I ordered a size too small and they very kindly replaced it for me. Conceals the chest very well. Very soft and breathable fabric, not tight, and by far the best binder I've ever worn. The sizes run small, so if you're in-between sizes or on the higher end of a size I'd recommend getting a size up. Very happy with my binder!
I. C. 5/5 Verified
BEST BINDER EVER!!! just this year i have tried gc2b, spectrum, and underworks binders and they did NOT live up to the hype at all and were so uncomfortable and didn't even work well for me. after that i basically gave up BUT finally, i decided to order this binder a few weeks ago and OMG it was the best decision i've ever made. this binder is so comfortable and flattens me like nothing else. the first day i wore it, after a while i didn't even realise i was wearing it until i looked at myself in the mirror and i was like DAMN I LOOK FLATTTTTTT (i said this to myself, not out loud lol). but 100% it was definitely the most euphoric experience i've EVER had. i'm so happy that i got this binder and seriously can't recommend it enough :))

Okay so I’m non-binary/transmasc and this is my first binder (besides wearing 2 sports bras!) Let me tell you I CRIED I was so happy. I have a 48DDD chest so I had little expectations for this. I ordered the 5x and it’s a perfect fit. I love this so much and I’ll probably order more!

I am in love! I’ve never written a product review but this is my first binder and it just feels so right.

I have never reviewed a product before but seriously, this is the best binder I've ever bought and I can't recommend it enough. I can't believe this isn't more popular as I've tried all the bigger brands and they don't even compare to this. 10/10.

My trans grandson is so happy to be able to conceal his breasts and still be able to move and breath freely. It certainly makes his school day much easier.
T. 5/5
It looks and feels so good! My chest size is 84cm and I bought size M. It's not excessively restrictive but I think if I bought the S it would have been too tight. I have a gc2b size S and it really hurts my armpits. Also, compared to gc2b, this one has a better waist elastic which sits better on my stomach and fits better overall. Highly recommend!

Amazing. It binds so so well and it’s super comfortable, came very fastly. I recommand taking one size bigger or else it might be too tight, I usually wear S, took an M size and its perfect. Thank you so much, I’ll sure buy from this store again !

(There are before and after pics for reference) This is so great in comparison to another binder I have. Straps are such a blessing lol. Flattens pry well. Especially if you are wearing layers or a hoodie or smth. Quite comfortable, kinda like a sports bra ig. My only complaint would have to be that the armholes are a little tight (might just be me tho) Oh! It also doesn’t leave as much of a weird bulge that my other one does. It’s also kinda a struggle to take off. Came early. Great product in my opinion
