Review: If you're large-chested transmasc: this is the one. Stop looking and buy this! - I am overjoyed with this product. I have a 32G chest and I have never been flatter. I own other Underworks binders and this one shines above the rest. The material is much more breathable and surprisingly comfortable (I'm neurodivergent and have super bad fabric sensitivity, so I was worried it would bother me. It doesn't!). HOWEVER!! If you have other Underworks binders, you might consider sizing up from your normal size. This material does not have much stretch to it and I had to struggle a little bit to get it on (I ordered medium). The armpits are also cut higher up on this model, which is great is you have a lot of breast tissue under your arms like I do. It does cut into the underarms a little bit but it isn't unbearable and I presume that it will soften up after a few wears. If you often disregard binder safety (as I am admittedly prone to doing), you will need to be more mindful with this product. It is noticeably tighter and more restrictive than similar binders, so you may need to take more frequent breaks. And a pro tip for binding bigger breasts in a half tank binder: instead of flattening your breasts downward toward the hem of the garment, try to flatten them toward your armpits (move them to the side of your body). This can cause bulging out of the arm holes in other binders, but I find that the higher cut of this one really helps prevent armpit bulging. I have been searching for the perfect binder for a few years now; this is it!!!
Review: made me almost completly FLAT - OK so, i ordered their econo chest binder two years ago and it did not bind AT ALL💔 a couple days ago i finally did some research on other underworks binders and found that the tri top has more stars and better reviews. i watched a youtube video reviewing the tri top and they said it has not one, not two, but THREE front layers (hence the name tri top). so i ordered it, i payed 10 dollars shipping because i'm impatient. It arrived the same day im making this review because i put the thing on and OML IT MADE ME ALMOST COMPLETELY FLAT!! and i can BREATHE??? 😭🙏🏻 i'm absolutely obsessed with the tri top binder. worth the money, it fits perfectly, the front is thick and sturdy, the back is stretchy, it's lightweight, did SUCH A GOOD JOB with the binding. what more could i want from a chest binder. 10/10 would recommend to anyone wanting to achieve an almost completely flat chest. for reference i ordered an XL, my chest all around is like 43 inches and im chubby. the ONLY issue i have is very small and hardly matters, it rolls up easy but when you're 4'11 and 180 lbs you're gonna face issues with binders no matter what 🥲 so yeah, GO GET THIS BINDER ITS AMAZING!! if something new about this binder happens or if my opinions on it change i'll update this review 😍‼️🔥💯

### ⭐⭐⭐⭐ Great compression but arm holes too tight
*by J***G on August 18, 2026*

I bought this based on the size chart. The compression is great! The fabric is stiff and thicker in the front. I wore this with a casual button up short sleeve shirt. The top edge of the front is high so I wore it buttoned up to the next to top button. So be aware not to wear it with lower cut shirts (like tanks wouldn’t work) or it will show. I think the top edge of the front has to be high like that to get maximum compression on the top of the chest. However I could only wear it for about 3 hours due to the arm holes cutting into my sides. I’m going to try the next size up though because the compression is that good.
