Need a high-compression chest binder that you don’t have to pull on? Our Side-Open Mesh Racerback Binder offers one of our strongest binds, with the added convenience of a hook-and-eye side closure. It's a favourite for people with limited shoulder mobility, anyone who finds pull-on binders difficult, and those with a larger chest who need a closer, more adjustable fit.

Designed for trans men, non-binary people, and anyone looking for a safe, comfortable chest binder, this style combines our signature Powermesh with a racerback design that distributes pressure more evenly across your shoulders. The adjustable side closure lets you easily put on this binder, giving you a snug fit around your ribs without compromising comfort.

We build our binders differently for your safety! Unlike traditional chest binders with rigid front panels, our binders are designed with stretch throughout the entire garment. This helps your chest expand naturally as you breathe and move, letting you bind tightly without feeling restricted or causing pain. It also creates a more natural-looking, “masculinized” chest, rather than simply flattening everything into a straight line.

Because the mesh fabric is semi-sheer, this compression binder is designed to be worn as an underlayer.

High Compression Without Sacrificing Comfort

Two layers of our signature Powermesh create firm, even compression while staying breathable enough for comfortable all-day wear. The lightweight mesh increases airflow to help keep you cooler than many traditional binders with non-breathable front panels, while the seamless construction helps reduce rubbing and pinching.

The racerback straps help distribute pressure evenly across your upper back and shoulders, while the hook-and-eye side closure makes getting dressed easier and allows for a more customized fit, especially for larger chests.

Designed for Easier Binding

Whether you have a larger chest, limited mobility, or simply prefer a binder that's easier to put on and take off, this style is designed to make binding simpler without sacrificing compression.

  • High compression with breathable Powermesh

  • Adjustable hook-and-eye side closure

  • Easier to put on and take off than a pull-on binder

  • Great for larger chests and people with limited shoulder mobility

  • Stretch construction lets you breathe and move naturally

  • Comfortable and safe for everyday wear

  • Seamless construction helps reduce rubbing and pinching

  • Safe to exercise and swim in

  • Semi-sheer mesh is designed to be worn as an underlayer

Why Choose a Custom Chest Binder?

A properly fitting binder is one of the most important parts of binding comfortably and safely. That's why every Origami Customs binder includes FREE custom sizing.

Every custom binder includes:

  • FREE custom sizing

  • Handmade in our Montreal studio, entirely by our queer and trans staff

  • Inclusive sizing with no added cost for larger bodies

  • Our Perfect Fit Guarantee. If your custom binder doesn't fit perfectly, we'll work with you to make it right.

NOTE: This binder does take a little bit of arm strength to close. If you don't need the side closure, you may prefer our classic Mesh Racerback Binder, which offers the same high compression in a pull-on style.

HOW TO MEASURE

Chest/Bust: Measure around the fullest part of the chest, with arms relaxed down at sides and without a bra. Keep the measuring tape parallel to the floor. Keep the tape comfortably snug but not tight, which will include measuring the space between the chest tissue. Do not squeeze the chest tissue flat.

Ribs/Underbust: Around your ribcage where a bra band sits. Measure on the exhale.  Make sure to measure under the breast tissue

Waist: Measure around natural waistline, which appears as a crease when bending to one side.

High Hip: Measure just over the hip bones, where the waistband of a low rise bottom would sit

Low Hip: Lift one leg to see the bend where the hip and leg meet. The low hip measurement is taken by measuring around the bum at this level. Keep the measuring tape parallel to the floor.

This is exactly what I wanted! It's very sturdy — if I'm pulling it over my head with the side already fastened, I'm not worried at all about damaging it. The side closure is a game changer; it gives me peace of mind to know that if I need breathing room or I'm overheating I can easily unfasten it. In addition, I can be sensitive to tags/zippers/tight clothing, but I find the side closure to be nearly unnoticeable once the binder is on.
The fit is excellent and I'm happy with the level of compression. For the record, I ordered for a rib measurement of 36 and chest 40; with the binder on its loosest fit (there are several rows of hook-and-eye closures on the side) my chest measurement is 38.

Favorite binder!

First time ever wearing a binder this comfortable! Does the job and doesn't hurt, and can wear it all day with no problems
Highly recommended, and love the custom sizing option

Great quality

This binder is great quality and fits well (I got custom sizing). My experience with the customer service was really great as well. They were even able to raise the neckline for me so less cleavage would show. I would highly recommend this brand to others.

The only thing to note is that if you have large breasts, keep in mind that a binder can only do so much. In bras I'm a size 34J or 34K, which means my breasts are far too large to ever look flat (sadly). So this binder ended up giving me a uniboob like a sports bra (maybe I'm not wearing it correctly?). This was unfortunately more dysphoric for me than wearing my normal bra (this might not be the same experience for you, depending on your identity and preferences). I've never worn a binder before so I don't know if this is normal. But I don't think you can expect to look completely flat if you have a large chest unfortunately

Best Christmas present ever

Kid #2 had tried a bunch of different binders and nothing was quite right. We ordered them a custom size, and it has been night and day since they opened it Christmas Day. The comfort they have personally with the fit has translated into happier teen. They feel like they look flat chested, their confidence level has sky rocketed, and they aren't hiding in massive oversized hoodies, but wearing tailored clothes that fit that flatter chest. They have been very happy with how well it washes, the fabric's feel and how it doesn't get out of place when they move around a lot. They are saving up for another one instead of buying game merch, that's how much they like it.

This is hands down the best binder I’ve ever used. The only thing I wish was different was the straps are a little too long for me. I have never had a binder work so well for me as I am 4’7 115 lbs with size 32H chest. This makes them look a lot less noticeable and makes me feel more confident. I am planning on wearing it when I get married. I need like 10 more. It is also super comfortable, breathable, doesn’t hold on to smell, and easily sleepable in (even though I wouldn’t do it every night).

Amazing!!

I love this binder, it's comfy and gives me the look I was hoping for! The only negative of it for me is its a little hard to undo, but besides that I'm pretty happy with it.

a.s.

the stitching was okay but it was slightly off? the left strap was closer to my neck for some reason so it pops out at the neckline of my shirts :/ the compression is fine. it pulls up my chest so you can still see when wearing tighter shirts. it took over 5 months to get here. can't believe i paid over $70 for this.

Too loose

It's a great quality fabric. But it's too big for me and slides it's way up my chest. I tried to messure myself to be accurate but it seems to need to go smaller.

Great concept, fabric too flexible

My son was excited to try this since he hasn’t had luck finding a binder that works with his body.
He feels the fabric is more like a bathing suit than a binder, so doesn’t wear it :(

Comfy fit!

I really love this binder and have ordered two more! It's comfortable enough for daily wear and I also use it as a swim top. The only downside is the production/shipping time, which was extra delayed due to staff sickness and material sourcing. My body size actually changed during the delay (HRT and exercise over 2.5 months) and the binder wasn't as tight as I would've liked so I've ordered new ones in custom size. I think the smaller size might provide the higher compression I'm looking for. The side close is great for folks with big/strong shoulders and I'm able to leave the top few hooks open to put it on and then finish closing.

It was worth the wait, the binder is soooo comfortable👌🏾❤️10/10

Feels like a second skin. I cried when I put it on. Fits so perfectly and although there's a bit of pinching under the arm where is does up, the discomfort is minimal. Honestly, I can't even compare it to other binders I've had since those were SO uncomfortable and downright painful. I was always so hyper aware of wearing them. This one feels made for me, like an extension of my body. I frequently forget I'm wearing it, which is in my opinion the greatest accomplishment of Origami! Thank you!

Super comfy. A little hard to put on but once I managed to close it all it was very nice and a good amount of compression for me while still being extremely comfortable and breathable.

Fits like a dream! I’m just building more strength to be able to close this one lol

10/10 would recommend for anyone that struggles with pulling binders over their head like me!

Love it!

I'm really pleased with the purchase of this binder. The free custom sizing is awesome and it fits greats. Feels really high quality and well made. I like the side open because it has 3 different hook placements so you can make it tighter as it streches over time. It definetely does take some effort to hook it shut esp. if you're bigger chested. But, it has really great compression. I was skeptical about getting a binder because I didn't think it would be any different than a sports bra but it really does make a huge difference. It's really nice to not feel my chest move at all. It takes my chest from 36" to 32". If you're considering buying this product I would say go for it!

Love this binder!

This was my first Origami purchase, and I love it. For reference, I have a 52" chest and a 39" waist, so based on the recommendations, this was the style I went with. It's also my first binder. Initially I was a little worried I would never get it on, because I wasn't strong enough to do up the hooks on the side, and I couldn't pull it over my head. However, after enlisting the help of a friend, I finally was able to get it on, and it stretched out enough after that first wear that I can now pull it on overhead and adjust the tightness on the side beforehand, which I love. I really like being able to undo the side hooks to remove it.

My only complaint is that, even despite ordering a custom size, the binder doesn't fit super tight around my ribcage, and depending on how I position my big bois inside the binder, sometimes it can result in an underboob situation when I raise my arms. However, this is a pretty small caveat, and otherwise I am happy with the amount of compression and feel very affirmed in this garment. It's super comfortable to wear almost all day; I only know I've overdone it because the straps will create angry marks on my shoulders. (Which bras used to do too. It's not a reflection on the quality of the binder, which is excellent. It's just Big Chest Problems.) I also love that this is easy to wash and dries quickly hanging up. I will be buying it again in other colours!

amazing <3

First time was a little hard to put on, but by the third, it was just like putting on any other kind of clothing that isn't just "pull over body".
It's super comfortable (in a tight way), fits amazingly well, holds everything in place, and is super affirming on top because the binding is really great, even for big breasts. The fabric is light and dries quickly, and also breathes, which is so awesome. I love my binder, and recommend it all the time.
It's the first binder that actually fits my body, feels good to wear, and also does its job. The craftsmanship is outstanding, too. And the people here are amazing.

Thank you for your work and everything you do, I couldn't be happier! <3
