Underworks FTM Extreme Tri-Top Chest Binder Top 983

Ill compare the gc2b binder and underworks for people like me who are wondering if they should get it. I have worn the binder for almost a week now and it's usually on for more than 10 hours (which I definitely do not advise, I have severe rib and back pain from that) First off- shipping was extremely fast, I live in southeast Europe and it came in around 5 days (had to deal with customs but that's because I ordered from the American Amazon like an idiot). You receive what you ordered, an underworks branded binder with the size and colour you chose. The binder itself is made out of some sort of rougher, mesh material, way more rough than the gc2b and slightly longer (I find that more comfortable). It was kind of itchy the first day, but I quickly got used and it doesn't bother me anymore. The shoulder straps and the neckline are more discreet, they're farther away from where your shirt neckline would be, the gc2b are really far up and could be seen under most of my shirts. The straps cause some tension and therefore my shoulders hurt ( kind of like I have sore muscles but that might just be me). Some people say the bottom of the binder rides up, that doesn't happen to me but everyone has a different body so take everything I write with a grain of salt. Lastly- the binder is, from what I can feel, a bit tighter than the gc2b, it does bind better (i have worn the gc2b one for more than a year and it might have been slightly stretched). But since its tighter it also causes more pain. I wear the binder, usually, for more than 10 hours, my back and rib pain has increased and there is added shoulder pain, sometimes it's almost unbearable. Otherwise the binder is perfect, I love it and I will definitely order more.

TL;DR: really good budget binder. Even with a larger chest and smaller frame it still does a great job flattening while the bottom edge stays flat on my ribs. Neckline bunches a bit so not for thinner, super fitted shirts **my sizes for reference: 29” ribs, 34” chest and got the Small size** I’ve gone on a binder blitz recently and gotten some from various companies. Honestly I didn’t have high hopes for this one since it was readily available on Amazon and didn’t cost a crazy amount. I’m glad I was wrong. This style (tri top) is the second style I have from Underworks, the first being the econo one (which compresses fine just the cut isn’t quite as precise as this one). I’ll say this was difficult for me to put on. Definitely couldn’t do it still being damp from a shower and I bet it would be hard to get off if I was sweaty. I can certainly feel the compression. I know having bigger boobs with a smaller frame I’m never going to be completely flat, but this gets me pretty darn close. While the bottom edge of this binder lays really flat on my ribs it still bunches a little, but not so much this it’s crazy noticeable through a t shirt (not super fitted). The neckline does bunch a bit more however, so I wouldn’t want to wear it under something very tight or thin. I didn’t do a lot of activity when I wore it but I would say definitely not for a high octane workout, at least if your boobs are that much bigger than your ribs because of the amount of compression. The straps do dig in occasionally on the shoulders but because they’re wider it’s not too uncomfortable until I can adjust it. After putting it on it was a bit of work trying to adjust my boobs only due to the arm holes being smaller (which hides my extra boobs spillage so not a sticking point for me) All in all I feel like it’s a great buy for the price and I’m shocked at the amount of compression I get

This binder fit really well, I am a 32 C and I am incredibly flat with this on! I really love the product and the material is pretty nice. It’s not very soft, but the panel in the front does its job well. It cuts into my armpits a bit, but not enough to bother me too badly. The neck and straps go kind of high up, so it’s not really suitable for low-cut shirts. That being said, the packaging is not discreet at ALL. Luckily for me, this wasn’t a problem, but something to keep in mind for those ordering. The product came in the original manufacturer’s bag, product label visible, with no shipping pouch or box at all.

Amazing binder, been using underworks for years. While I do have a small chest la it may not work for everyone. It binds me flat and very natural looking. It feels a lot like a bathing suit and after a bit I don’t notice I’m wearing it. The fit was true to size too.

My chest is 41DD - which would be very hard to bind. However, this binder made me pretty flat! I have no complaints about that. The material is pretty uncomfortable though, almost like a potato sack. However, the sizing wasn't very accurate to me. According to the guide, I'd be a size L. I went up a size and got an XL, and it was still too tight. I've been wearing binders for years now, so I'm familiar with what's supposed to be a safe amount of compression. I'm going to get a return and attempt to size up an XXL. I'll update with new information then!

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!!!

HELP! I restocked the XS model 983 i always buy but it’s somehow longer than the small size? I have been buying XS for years and they are always the same i don’t know what to do i dont fit the regualr small only the old XS sizing when did they change this ???? why not update the customers before they buy???

Hands down the most effective binder I've tried. It flattens me pretty much completely and keeps everything in place even while I'm working and moving around a lot. These last for ages too, I have some that I've been using for a couple years and haven't really noticed any loss of effectiveness. Maybe not the most comfortable in terms of fabric softness but what binder is comfortable if we're being honest lol

Good

This binder is amazing for binding even very large chests and making it look natural. It performs significantly better than most other binders I've tried. regular use would need to be worked up to as it can become uncomfortable fairly quickly, so just make sure you wear it in before longer periods of wear

It's best you order a size up and it's hard to get on but once it is it's comfortable,you breath fine and binds amazingly

I’ve been using this exact binder for years and it’s never faulted me. It’s less prone to wearing out than other brands like GC2B or spectrum, the material allows more breathable meaning I don’t get that horrible sweaty feeling with nowhere for it to go. It binds much better than other brands for me, and I can wear it daily for 8+ hours without discomfort. I’ve had several of these in the span of a decade and never had any issues with seams ripping and even my most worn out binders still work surprisingly well for days I’d rather take it easy. The material might be a bit of an issue for some people, but for me I prefer it over the more swimsuit esque materials of other binders. It can also dig in a bit at the sides, but it’s never caused me more discomfort than say a sports bra.

Passt perfekt.
