Product name: Tri-top Chest Binder (Underworks)
Manufacturer’s website:
Chest size at time of use: 12C (Australian measurements) – around 32.5 inches I think.
Comfort: 3/5
  • This is my first binder, so I have nothing but cotton sports bras to compare it to, but I’m not finding it very comfortable. When I first put it on it made my back ache and my breathing felt constricted, these both passed within a half-hour or so, and I expect were factors of being unused to wearing something this tight. The top stops at the base of my ribs, so doesn’t compress my stomach at all, which is good. My big problem is that some of my chest tissue has been pushed out of the arm-holes and I can’t seem to adjust myself in any way to stop this happening. This looks like under-arm fat, which isn’t nice, and the arm-holes themselves are digging quite uncomfortably into these rolls of tissue, bringing overall comfort down. I won’t be able to wear this every day, and I don’t think I’ll be able to wear it while doing anything very active, it cuts in too much. According to the measurements on the Underworks website I have the right size for me, so I think it’s just a factor of the design versus my chest.
Effectiveness: 5/5
  • I don’t know how it will bear out over time, but brand new this is the flattest I’ve ever been since before puberty. Brilliant.
Discreetness: 4/5
  • Under dark and/or loose-fitting shirts you can’t tell I’m wearing anything at all. In v-necks or open-necked button-downs the little bit that shows just looks like I’m wearing a tank or undershirt underneath. Under white/translucent shirts however, it can easily be seen, and it’s obvious that it only covers my chest. I don’t wear tight shirts, so the shape of it showing under tight shirts is not a problem for me.
Overall : 3.5/5
  • This was really, really difficult to get on. I got a small, which was the correct size for me according to the sizing on the website, and once on it fits fine, but I had a LOT of difficulty getting it on over my shoulders. It was awkward and kept bunching painfully around my upper arms and getting stuck. I eventually managed to get it on without actually straining my shoulder, but I very nearly gave up. Definitely something to have a helper on hand for if you can, and not good for anyone who is prone to dislocating their shoulders or needs to get dressed quickly.
    It’s great for flattening my chest, but being so hard to get on (and I assume off, I haven’t tried that yet), and the way it cuts around my arms really brings the rating down IMO. I can’t wear this every day, I’ll keep it for the days when my need to be as flat as possible is stronger than my need to be physically comfortable.

Product name: T-Kingdom M801 binder
Manufacturer’s website:
Chest size at time of use: Small (28-30 inch chest)
Comfort: 5/5
  • I’ve never worn a binder before I bought this, and I’m still not entirely used to the way it pressed my chest and causes that compressed feeling around my chest and lungs.  I assume this is to be expected, so taking this into account I’ve found this binder to be incredibly comfortable.  It still takes me maybe an hour or two to get used to it (I do not bind frequently), but once I do I even forget it’s there!  Besides the obvious binded feeling it feels incredibly natural and comfortable to wear.
Effectiveness: 3/5
  • The only thing I find lacking in this model is the fact that I seem to “mushroom” up after I’ve worn the binder for a while; it seems like there’s a lot of bulge at the top of my binder from where my chest has situated itself.  This could be because it has a zipper in the front, or perhaps because I would be better suited for a medium (I tend to be in between sizes).  Other than that it does the best with what it’s given.  With the proper clothing I appear very flat-chested.
Discreetness: 4/5
  • It’s not strapless, but considering this it works very well when covered first with an undershirt.  The only problematic thing is the front zipper.  It’s not a huge zipper, it’s very discreet and unless you were looking for it you’d never notice it under the clothes.  However, I have noticed it when paying very close attention to it.
Overall: 4/5
  • While I’m overall satisfied with my binder, I will probably look into buying either a velcro binder or one without velcro.  I feel that the effectiveness of my binding may be increased if given a different type of binder, but I’ll just have to see.  But as a first binder, I am definitely not disappointed with it!  Their website is also very user-friendly and was very helpful for a first-time binder buyer.  I highly recommend T-Kingdom.

Product name: 988 tank top extreme compression vest

manufacturer website:

Cup size at time of use: B or C

Comfort: 4/5

  • The under-stitching has a tendency to rub kind of hard, but overall its a very nice feeling. Wouldn’t recommend sleeping in it.

Effectiveness: 5/5

  • I am completely flat chested with this shirt on.

Discreetness: 4/5

  • I wouldn’t wear it with v-necks since the fabric doesn’t exactly feel like cotton, since it is spandex. Otherwise you cannot tell you have a compression vest on, looks like a regular t shit.

Overall: 4.5/5

  • I say [four and a] half because the price for one single item is pretty high, but then again having my dignity and self image restored to normal is priceless. This shirt works for extreme gynecomastia.

  • I like it that it’s not racer back (like most sports bra). From under my clothes, it looks like a singlet, which is great! Cos I hate it when people could see that I am wearing a sports bra.

Overall: 4.5/5

  • All my life, I have been looking for an effective and comfortable binder. I was sixteen then and I have only tried binding with bandages (I’m not kidding…) the old school way ONCE. It was effective and very convincing… but i could hardly breathe. After so many years I didn’t dare to try it again. I resorted to wearing sports bra (one size smaller than I should) to flatten my chest. It did reduce my CUP C chest to a CUP B I think.
    And then this year, after more than ten years of wearing sports bra (which didn’t keep me very happy… I still had to wear big and thicker clothes to hide my chest…), I finally found the best binder ever! It works! Reduces my CUP C chest to look like a CUP A! Although my chest is not completely flat like a man’s, it was very comfortable! And i’m so glad that i chanced upon this binder review blog! Hey great job! Keep up the good work! It’s really something good for the community ya… =) Because I really think that binding too tightly could be… erm… maybe a little bad for health? So I’m happy to share that achieving the appearance that we want could be attainable with a little compromise too! =) At least… I think my chest looks flat enough to be convincing! And i feel very confident now! heh!
    I just wished that they could have more designs and colours soon! Oh and i did had some trouble wearing it and pulling it over… but now I’m an expert!

Product Name: Double Front Compression Vest (#997)

Manufacturer’s website:

Cup size at time of use: C

Comfort: 4

  • This was the first binder I ever bought. The first time I tried to put it on, I thought I was going to be suffocated, but it got considerably more comfortable after I wore it a time or two. It is really long though, and I usually pull it down over my hips to slim them a bit too, but it rolls up. Bleh!

Effectiveness: 4.5

  • A 4.5 is really most appropriate for this one. I’m very flat with it on, but sometimes if I’m going to wear a slightly looser shirt and am not worried about lines, I’ll wear a tight sports bra under it and it will make me completely flat.

Discreetness: 4

  • The top seam around the collar shows sometimes for me, and I wouldn’t wear a white top with it because I think it’d show through too much.

Overall: 4

  • Overall, this was a good binder to have a first experience with. I just wish it was a little shorter!

Cup size at time of use: 40 C

  • Product is best worn with a shirt underneath it to protect your underarms from being rubbed. I wear an off-brand underarmour style t-shirt for ease of putting the binder on and for comfort.

Effectiveness: 5

  • This does not give a completely flat chest although I have noticed that in some button down shirts my chest looks too flat compared to my physical size. Larger men often have larger chests and this binder took me from being gender in question to being harassed for not belonging when in the women\’s restroom (on the few unfortunate times I have been forced to use it). It removed any question of my gender in all public places.

Discreetness: 4

  • The top rides too high to be worn without a t-shirt over the top. There is a little bit of bubbling at the top which is fine in nearly every circumstance but made me a little self conscious at water parks and swimming pools where your shirt hugs tight when wet.

Overall: 4

  • Again this product did not make me completely flat as I am a larger guy. I ordered according to the sizing suggestions and think I could go a size down for a flatter affect. I absolutely plan on buying this in the future even though there are some negative aspects. I was also pleased with the price for the effect.

  • Just feels like a tank. A little tighter of course but nowhere near uncomfortable. very cool even in the heat of summer.

Effectiveness: 4

  • Flat. Not Non-existant, but with my size i can get away with it. I\’m quite Buff so they just look like pecs

Discreetness: 4

  • Looks like a tank. If you wear it under one it just looks like your going for that layered look

Overall: 5

  • Great if your very small chested like me. As the Testosterone builds my pecs up its harder to hide my chest and still look muscular. This does the job nicely.
