The person I bought this for loves it. It binds their chest not only better than the tightest they ever wore a wrap or ace bandage (which is effective but so uncomfortable and unhealthy), AND manages to be very comfortable. They can wear it without noticing, and just feel comfortable - without constant feeling of gender disphoria.
The straps also are much flatter and more discrete than alternatives, so that a very thin shirt can be worn without much worry.
The only drawback is the bottom of the binder is visible in front and back through a shirt, reminiscent of a bra. This can be softened by undershirts, thicker shirts, or perhaps a loose wrap or strip of tape around the binder's bottom.

Okay, so I'm not ftm, but still under the trans umbrella. I bought this for myself because I wanted to appear more flat chested than normal, as I have pretty large boobs for my age. It flattens okay, but not as much as I want it to... and not as much as I was expecting. Anyone with a bigger chest may want to reconsider and search elsewhere, however I don't mean this in a negative light, if you can't find any other binders that would work, you can wear a tighter sports bra underneath, which makes you more flat than just the binder alone. Still a great product!

I've owned a few binders in the past and this one is just crazy tight"¦ I couldn't get myself to wear it after the first time using it because of the pain and difficulty putting it on. I suggest sizing up if you want to buy this because while I had a bad experience, it definitely serves its purpose.

i will start off by saying that i am a double D cup size and i wasn't really expecting to find a binder that really makes a difference. i'm about average sized in every area except for my chest though, so i'm not sure if this binder will work well for individuals who are a little on the heavier side.

i bought a size large in the grey. i found that it was easier to clip the side where i wanted it to be and then slid it down over my head. it took a moment to figure out where my breasts were supposed to fit, but i found that letting them just hang naturally the way they usually would without a bra and then putting the binder over top worked well. at first when i put on a shirt, i looked like a sausage shoved into a casing that was too small. not flattering. i remedied this by putting a sports bra over top and that seemed to do the trick. as i write this i am sitting at a desk and have had it on for two or so hours. and man, this thing is super comfy.

if you have a large chest and put a shirt on over this it WILL make your shoulders look pretty wide and chest look like it's made of solid muscle. think abby from the last of us. i'm not a big fan of that effect, but putting a loose hoody on over top makes my chest look like it's barely a B cup size. note: if you have a large chest it will not make you look totally flat. that's simply not possible. however, it DOES make your boobs look significantly smaller.

Comfort: 5/5
Stretch: 5/5
Flattens: 4/5
True to size: 5/5
Style: 4/5 (i think it would be perfect if the binder was longer)

Trans/nonbinary user. Ive had this product since the end of July. I only have some experience with a used high quality binder thats slightly too big for me to compare it to, which i have had for nearly the same amount of time. This is very much a "babys first binder" as I wanted to see if investing in a more expensive binder eventually would be worth it.

Pros:
-Compression isnt uncomfortably tight, easy to wear for hours without thinking about it
-Doesnt ride or roll up
-The soft material above the compression part of the binder creates a sort of illusion of pecs on small chests as the fat gets pushed/spread out.
-Gets my chest completely flat

Cons:
-Its not a breathable material, you will sweat
-The line where the compression begins is visible as is the bottom of the binder in light colored shirts and tight shirts.
-the stretchy material at the top may create a shelf/corset boob effect on bigger chests rather than the pec illusion im experiencing
-the material of the compression is not comfortable against the skin, should have lining tbh

Overall, for the price, it did the job and gets 4 stars for a quick solution to dysphoria. If you are small chested and think a compression sports bra is enough/dont think its worth it to spend the money on a brand name binder, i recommend you give this binder a try so that you can make an informed investment.

This would definitely work for small chested cosplayers easily.
