Very soft!
I must have ordered a different model than I had before because the material of this binder was surprisingly very soft! The front inner lining of the chest binder has a very soft material which is great if you’re like me and you have sensitive skin. This binder also doesn’t roll up all the time like I’ve found the other models to do. The only downside is that I’ve found that it’s not quite as restrictive as my other underworks binders and therefore, as a big chested pre-op ftm dude, there’s still a faint silhouette of my chest through the binder. This isn’t a problem when wearing baggy shirts though, which I do all the time anyway haha Very good binder, I recommend it as a more breathable and softer binder. I’d buy another one of these to keep for days where my sensory issues flare up. Very good binder!

Good but check the updated size!
Underworks binders are still one of the best options available and this one is no different. Material isn’t as rough or low quality as I was expecting from some of the other reviews. One complaint I do have is that I didn’t notice the updated size chart and instead went off the size indicated next to the S,M,L etc which weren’t actually right. So I ordered a medium when I should in fact be a small however it still binds well enough so I don’t mind too much. Won’t go through the hassle of sending it back, will order a small in future though. A binder won’t get your chest completely flat if your bigger chested however stick on a baggy t shirt and you can’t tell. With this being the first binder I’ve bought I can’t compare it to GC2B or the other Underworks binders but for the price this one is good, just make sure to check your sizing against the updated chart!

Underworks never fails
I've had underworks medium - XL and they never disappoint. Thanks so much!

Good if you don't care about stealth
The wide back coverage makes it so that there's no curved outline when you wear thin shirts, but it rips at the sides if you're not careful when taking it off. However, the straps aren't too wide, so you'll see them peeking out from the opening of the shirt if you don't wear something with a closed neck.

Amazing
This is perfect! Bought for a friend and made a DD chest almost flat! Amazing quality and very true to size. No restrictions on breathing at all. Very happy

Probably worst binder i’ve owned
After i noticed GC2B products getting worse, i thought i’d try a new binder from a trusted company. I checked my size and brought the same style in which i’ve brought all of my others and the quality is terrible. Very uncomfortable, poor finish around the edges so if you wear a shirt the seams under your neck and above your chest show and overall does an extremely poor job in my case. I brought the small so it may work better for other people who use different sizes but if your looking for a size small, i’d recommend looking else where.

Just don't buy it
Itchy material gets wrapped up and hard to put on does bind a bit but still noticeable and that's only on my 34b cups waste of money wish I could just find a good binder

Works well
- Binds well - Quite tight, gets uncomfortable after a few hours - I can personally ignore fabric, but the back panel may be uncomfortable with those with strong sensory issues

Great on a budget binder with a thick edge seam
*For size reference: 5’6”, ~110lbs, 29” rib measurement, 34” chest measurement which makes me a C-cup but close to a D* TL;DR: get the correct size for the best bind, could see the material being an issue for people with more sensory issues (the edge seam is thick and the outer layer doesn’t always lay perfectly flat) but for under thicker T’s or shirts with patterns it’ll work great. Second time I’ve ever worn a binder, but this one is the correct size (first was one size too big) and can def see more flattening. With the extra flattening comes the warning of NOT working out/heavy activity while wearing this. I had a slightly larger size on yesterday (different brand) and could easily see doing some light exercises, nothing crazy. But with this I can feel the compression more and am being mindful about it as the day goes on. I have bigger boobs that I’ve never felt comfortable with but a small frame so it’s been tight sport bras for most of my life. Finally thought I’d give binders a try. While this one does bind me the best so far I’m only wearing it under a T-shirt. If I pull the shirt tight against my body I can definitely see the outline of the edge seam so keep that in mind if you plan on wearing it under thinner or more sheer clothes. Under a thicker shirt/sweater or anything with a pattern I think it’ll be hidden pretty well. While wearing a size too big (which is better for more activity) yesterday, I did catch myself hunching over a lot more because I felt like my boobs were going to start sagging and I’d have to go readjust. But so far with this one I don’t feel like they’re going to go anywhere. Haven’t done much arms-over-my-head movements to test that though lol. Overall I feel like this will be a great binder if you’re on a budget and don’t mind the thicker edge seam

Gaat heel lang mee
Ik was het altijd op 40º en niet in de droger en ze gaan heel lang mee. Maar ik heb zelf geen ervaring met het dragen. Wel goede voering aan de voorkant, lijkt katoen (oftewel niet zweten) achterkant heeft geen voering
