  • Best of the bunch
Size: Large Color: Black
I’ve tried other models of this brand, as well as lots of other brands. This particular one, is the best one I’ve ever wore. And would totally recommend it to anyone with some Gyno problems. I’m 6’2” with a muscular, slimmer type build, and the Large fits me perfectly. They last long too, thousands of washes and hot dryers, and they come out perfect, and never stretch out. Even though I buy new ones, the ones I bought years ago are still worn quite often. They really don’t wear out much at all. They do break in a bit after a while, and become more comfortable. But keep their shape Happy w these! ... show more

  • Maximum Safe Binding
Size: X-Large Color: Black
I'm a large (overweight) FTM individual who is pre-top surgery and hands down Underworks has the best binders that work on me. I've tried a few other brands before that are meant for smaller people but just 'up-sized' to fit me, and they were basically just an undershirt, which any dude with excess breast tissue can tell you does not bind at all, just kind of lays over your chest. When you're someone walking around with DD sized chest AND a big waist, you go in knowing it's never going to be perfect. Nothing short of top surgery can do that. This won't turn you into a male model, but it will flatten your breasts down to match your belly, giving you a flat (and thus more masculine) chest. Now I can be a normal fat dude and actually leave the house. If you're a cis-guy with just 'some' breast tissue from being over weight, then this product would work even better for you. Smooths out the lumps and you probably have a lot less of a hurdle to overcome in the first place. Hey, if it's working for the transguy with the DD chest, it's probably going to be a godsend for you. Fits true to sizing. Measure yourself before you order. I listened to other reviews and I wear a thin undershirt beneath the binder to combat chafing. Never had any issues with roll-ups or sliding around, but I also don't wear the binder by itself so who knows? Only con I can think of is that the neck is a little wavy on the front, especially after extended use. Might look weird under low cut shirts.... but if you're wearing this you're probably not trying to draw attention to your chest with low cut shirts anyway (at least I'm not), so YMMV. All in all as a transman this product helped me overcome a significant portion of my dysphoria, enabling me to get out of the house more and stop stressing at work. Very glad I found it. ... show more

  • Good for FtM binding, but not great
Size: Large Color: Nude
Bought this for FtM binding, worn it about 10 times now, and it works for that. Goal achieved. It gives a good, flat profile, doesn't do the pigeon breast thing, and does nice overall compression on the rest of the torso. It's far better than the jerry-rigged items I've used for binding for ages and seems sturdier in construction and like it will last a good long while. All good things. I will likely buy more. That said, it's not perfect. As others have mentioned, the fabric leaves a lot to be desired, texture-wise. It is a stiff, tight-weave mesh-like material (nylon/spandex). The back is one layer and the front seems to be two. It is rougher than all of my prior compression or shapewear garments I've worn for binding. I am not sensory-sensitive to this sort of thing, but I can easily believe it could be a problem for many who are. To its credit, it gives a good, consistent stretch/constriction and doesn't seem like it will stretch out quickly. Again as others have mentioned, the seams have a "bacon collar" issue. Also, the cut of arm holes assumes a large-armed and broad-backed person — neither of which I am — so there's some considerable gaping there for me. If you're trying to go superstealth and don't have a broad back or thick upper arms, both of these details mean it will show a bit under your shirt. The measurement instructions given worked PERFECTLY for me where the chest is concerned, however it is EXTREMELY long. YMMV, but I am relatively short-torsoed and have to fold back 4" of the bottom and it still tucks deep into my underwear. I plan to hem it to fit my back length better. Overall, I'm pleased and will likely buy more, but it's not perfect. I picked Underworks for the good reviews I got from other transmascs, the fact there is a return policy (as compared to a lot of the popular binder makers that offer shop credit at best), and the straightforward measurement instructions (that proved to be accurate IME). In all of those areas, this product delivered. ... show more
