Surprisingly comfy and fits like a glove!
This is my first binder and I was a little afraid at first to put it on. After hearing all the things that could go wrong from binding, like trouble breathing, how could I not be at least the tiniest bit nervous? But after wearing it to work for a week, I work in a factory, I was surprised by how comfortable it was and that I had no issues breathing in it. I am 5'6 with a bit of a chubby build and DDs, so I got a 2XL and it fit perfectly. The compression feels really good and made my chest flat enough to look like pecs, as long as I pulled the tatas to the side, and the spandex in the back had the right amount of stretch to give ample mobility. The quality of the fabric and zipper is really good. However, the printed tag on the inside rubbed of after a few days of wearing it. I don't blame the company for that, I blame the amount I sweat while I am at work XD. The only issue I have is that the bottom rolls up when I sit down, but that might just happen because of my chubby tummy and my bad posture. Wearing a thin tanktop or spaghetti strap under it kind of helps with that issue. Overall, the best first binder to get for the price and it does exactly what it is supposed to while making you look good.

Good Golly
So, my mom got me this for a Christmas gift, and holy hell it’s amazing. It makes my chest so flat, and it works better than the binders I e had in the past! It’s comfortable, it’s breathable, I don’t feel like my lungs are being squeezed. It’s truly amazing! Thank you to the designers for making a binder that works for me and many others!

some zipper trouble, but overall good
works well! flattens more than other binders ive tried, however after some time like all other binders it just isnt as tight as it used to be but honestly i think the time for the price is pretty reasonable. fits exactly to the measurements, is extremely breathable, and the shape makes it more convenient than other binders ive tried w different clothing garments. sometimes u can see the zipper underneath the shirt but not very well and i wear a chain anyway so im betting people assume its just a cross or something if they notice at all. my only real issue is sometimes the zipper has issues where right after i put it on the bottom piece slips out of the catch and its quite difficult to fix but it doesnt happen often and it isnt broken:) i have reccommended this product to others and i would continue to

Good beginner binder, but comfort is sacrificed for mediocre compression
I am AFAB 5'4 and weigh 160 pounds, 36DD. I bought a M and a L I recently 'graduated' from my beloved Wonababi binders to 'real' (expensive) binders from Spectrum and Gc2b, and I have to say I'm still pretty happy with these. I'd bought them initially because they were more affordable and I didn't know my size, and I can safely say they will continue to serve as binders on my off days. Pros: decent compression for the money taking it off in one swift unzip at the end of the day is delightful good length in both sizes (most binders are a little too long for me and roll up at the bottom) don't get super stretched out by the end of the week (I would alternate daily between my two pairs) Cons: zipper mound can be seen through thin shirts very tight on my neck and shoulders (I have wider, beefier shoulders, though) NOT a fan of the racerback style at all, very uncomfortable on shoulders the L had poor compression but was more comfortable (still pinched), and the M had decent compression but was even more uncomfortable (I would struggle zipping it up if I was sweaty or freshly showered, and it would make red lines on my shoulders) the size rubbed off of the back panel almost immediately (I just wrote it in in sharpie) TLDR; I liked these but they are not priced as economically as I would say was worth the quality. I often still looked like I was wearing a sports bra, although my chest was much flatter than without a binder. For those with bigger chests and shoulders, definitely size up if going to purchase from this brand. Shipping was great and fast.

Absolutely shook.
I will be buying this in more colors! I’m a 30H bra with 650cc silicone breast implants but like to present as masc and androgynous on occasion. This binder has exceeded my expectations. I got a size large and it fits great! Tbh I probably could have sized down for a little more compression. My bust is 38 inches and under bust is 26 so it’s a bit baggy under the bust. If I wore this under a tshirt it would just look like I had pecs. My only complaint is I wish the neckline came up a little higher in the front because from above you can see some cleavage. The material and compression level is very comfy though.

Comfortable in 4/5 aspects
Update after e months, zipper broke. Zipper broke BAD Okay, ignore my body shape best you can, i wanted to show what i liked and didnt like about this binder. Its comfortable truthfully, i wore it all day and didnt ever struggle to breathe or move at all. It did roll a little, but thats bc im shaped like a bag of russet potatoes. All in all, i think ill get a couple more. These seem like a reliable, breathable, casual binder that could even be used in binding breaks. Not the tightest bind ive ever had, but the easiest to get on and easiest to forget about. Im sorry i dont have a better picture of how it flattens me out, but its an easy going compression that definitely reduces my gender dysphoria, PLUS it came with some fun, gay stickers. The most important thing that i didnt like was how it seemed to cut into me in the back? The garment isnt too small, so im not sure why it did what it did. I weigh ~240, and have a40D/42C bust. I typically wear a 1x in US mens shirts, 2x in US womens shirts, and ordered a 3x in this binder.

Really good but awful on the armpits
I love this binder so much and it flattens my chest a lot but the (stitching part? brim?) is always rolling and HURTSSS to move in most of the time. I pull it down constantly. The packaging is super descreat it comes in a gray plastic mailer with no indication it’s a binder, and once you open it it has a blue wannobabi package with the binder a poster and pride stickers! (I still got outed tho because of those darn Amazon notifications) the binder was so cheap what? Like most are 50-60$ this on3 was 30! Also it migh5 be hard to get into at first but once you wear it for a while it is easier, and it’s realy easy on 5he lungs. Please! Fix the armholes but otherwise this it 4.5/5! Update it broke after like 2 days writing this review I would like a replacement but it it too late, I would give it a 3/5

Fits like a glove
My measurements: Height 5'6, Weight 112 lbs, Shoulders 15 in, Chest 31.5 in, Bra size 32B. I bought a size medium. Fits amazingly, and for a binder, is insanely comfortable and easy to put on. My only other try at binders years ago was an Underworks binder, but it was so uncomfortable and difficult to put on I gave up and thought binders just weren't for me until this one. My chest is just small enough to be able to put on the binder like a jacket and zip it up, but as someone else here noted, if you have a bigger chest you may still have to zip up the binder first and put it on like a pullover. The zipper feels very strong and I have no worries about it breaking from the pressure. Once on and adjusted, it makes me nearly completely flat, much flatter than a compression sports bra. No problems breathing or feeling stuffy even after hours of wear. The only discomfort I have is that it cuts a little too high in the armpits, and since the shoulder straps are kind of narrow it does put pressure on my shoulders. Nothing I can't stand but it's noticeable. I do, however, like that the straps are a little further out than other binders so they show less at the shirt neck hole. The only real negative about this binder is that you can see a bump under my shirt where the very top of the zipper is, and the upper edge of the binder can also kind of be seen. It's noticeable with a regular t-shirt on but can't be seen when wearing a button down shirt. Since I wanted a zipper binder for the ease in taking on and off, I see it as a trade off that's worth it for me. If that will bother you or make you dysphoric though, definitely just get a pullover. Overall, incredibly happy and would definitely buy again!
