Chest Binding 101: Everything You Need To Know
Chest binding means flattening your chest with a compression top or binding tape so it looks flatter under clothes. For a lot of us, a flatter chest means less dysphoria and less stress about leaving the house. Binding the wrong way can hurt you, though, so this chest binding guide covers the basics: binding safely, picking a binder, putting it on and taking it off, care, and where to get one if money's tight.
The short version: wear your measured size, keep max compression to 8 hours or less, and never sleep in any binder.
What is a chest binder?
A chest binder is a compression top that moves chest tissue down and out toward your armpits for a flatter look. A real binder spreads the pressure evenly, so you can still breathe through a normal day. DIY methods don't.
Binding safely
Never bind with ACE bandages, elastic bandages, duct tape, or sports tape that isn't made for chest binding. They tighten as you breathe and move, and they can break ribs, damage organs, and seriously restrict your breathing. However bad the dysphoria feels today, your body has a future. Look after it.
- Know your binder's limit. Max compression binders: 8 hours or less a day. Cotton binders and the Sports Bro can be worn all day. Either way, breaks help.
- Never sleep in a binder. You breathe differently asleep, and binding overnight can cause problems like sleep apnea, poor sleep, and strain on your heart over time.
- Skip max compression for workouts. It limits breathing and movement, raises your injury risk, and can trigger asthma. Wear the Sports Bro instead. It's light to medium compression, made for the gym and the pool.
- Buy your measured size. Sizing down won't make you flatter. Measure around the fullest part of your chest with a soft tape, level and not pulled tight, and use the binder size chart. Between sizes? Size up.
- Check in with your body. A binder should feel firm, never painful. Every couple of hours, sit up straight and take a few deep breaths. Pain, tightness, or numbness means take it off.
- Stretch. Roll your shoulders, reach overhead, do a seated twist. A couple of minutes helps your circulation.
- Breathe deep a few times a day. Push all the air out, breathe in through your nose (belly first, then chest), hold for 3, and breathe out through your mouth. Do three or four. A few hard coughs also help clear fluid that builds up.
- Watch your posture. It's easy to hunch to ease the pressure. Keep your shoulders back and down and your head over your neck.
- Take it off right away if you get shortness of breath or can't take a full breath, sharp or lasting pain in your chest, ribs, or back, dizziness or feeling faint, numbness or tingling in your arms, or a rash or skin irritation.
Which binder is right for you?
| If you want | Try |
|---|---|
| Everyday wear, smaller frame | Short Tank or Cotton Short Tank |
| Broad shoulders or an athletic build | Short Racerback or Cotton Short Racerback |
| A fuller chest or curvier body | Long Tank or Cotton Long Tank |
| Hot weather or sensitive skin | A cotton binder or binding tape |
| Gym and active days | Sports Bro |
| Swimming and beach days | Binding tape (it's waterproof) or the Sports Bro |
| The flattest look, for photos or events | Long Tank or Long Racerback |
Our binders
Every TGS binder comes short or long, in a tank or racerback cut. Short ends below your ribs and is easier to tuck. Long runs to your hip and won't roll up. Every binder gets a free size exchange within 30 days.
Max compression
Our firmest binders, with a stiff woven inner panel that does the flattening. Wear them 8 hours or less at a time.
Cotton
Medium compression in soft, breathable cotton, with no stiff inner layer. It's the one we suggest for first binders, warm weather, and anyone who finds synthetic binders itchy. You can wear cotton all day. Lots of people own both styles and switch by season.
Sports binder
The Sports Bro is light to medium compression in a quick-dry, moisture-wicking fabric. It's the one to wear if you want to work out or swim without skipping binding, and it's fine for all-day wear on hot days. Recovering from top surgery? Ask your surgeon before you bind.
Binding tape
Binding tape is a stretchy cotton-blend tape with a waterproof, latex-free adhesive. It shapes your chest without a garment, so you can breathe and move freely. It's great for the beach, backless or strapless outfits, hot days, and anyone who can't stand the feel of a binder. It comes in 3", 4", 5", 6", and 8" widths, and nobody else makes the 8".
Tape can stay on for 3–5 days at a time, and let your skin rest in between. Before you start, read how to bind with tape and the binding tape FAQ, or shop every width.
How to put on a chest binder
Binders are smaller and tighter than a tank top, so the first few tries can feel like wrestling. This makes it easier:
- Turn the binder inside out and upside down.
- Step into it and pull it up to your waist. It's still inside out and upside down.
- Use the armholes as handles and pull the top up toward your shoulders.
- Put your arms through the armholes.
- Reach under and gently ease each side toward your armpit.
Go easy on that last step. Don't yank hard to the sides or down. You want a flat, even chest, not a uni-chest in the middle.
How to take off a chest binder
Taking it off after a long day is one of life's underrated pleasures. To do it without getting stuck:
- From the bottom, shuffle the binder as high as you can, mostly up into your armpits.
- Find the bottom edge behind you and untwist it.
- Cross your arms, grab both sides, and wiggle it up your back.
- Grab the back from above and shift it over your shoulders.
- Pull it up and over your head. Grabbing both sides of the bottom helps.
You'll find your rhythm after a few tries. Rocking your shoulders side to side helps. It sticks more when you're sweaty. Worst case, ask someone you trust to help with the last step.
Binder care
Sweat and dirt break down the stretch in compression fabric, so washing keeps your binder working longer.
- Hand wash cold with mild soap. The machine wears out the stretch faster.
- Cold water only. Heat breaks down the compression.
- Hang or lay flat to dry. Never put a binder in the dryer.
- Check it now and then for thin fabric, frayed seams, or lost compression, and replace it when it's noticeably looser.
- Rotate two if you can. Both last longer, and you always have a clean one.
Free and low-cost binders
Transition gear is expensive, and a binder is one of the most important pieces for a lot of trans masc people. If you can't afford one right now, you've got options.
- Point of Pride's free binder program sends binders to people who need them.
- The National Center for Transgender Equality has know-your-rights guides and resources.
- Lots of people pass on gently used binders after top surgery. The r/ftm subreddit has a monthly buy/sell/trade post, and you can sometimes get one for the cost of shipping.

Max compression: 8 hours or less at a time, with breaks when you can. Cotton binders and the Sports Bro can be worn all day. Never sleep in any binder.
Yes, in the right one. The Sports Bro is made for the gym and the pool. Max compression binders aren't. Binding tape also works under swimwear.
Neither is better overall. A binder is easier for everyday wear. Tape works under tanks, swimwear, and open backs. Read how to bind with tape before you try it.
