Gender-Affirming Essentials: Binder, Gaff & Packer Fit and Care
The right gender-affirming gear can make daily life more comfortable and confident. But fit and care matter: a binder that is too small or a gaff worn too long can cause discomfort or harm. This guide covers binders, gaffs and packers: how to size them, wear them safely and keep them in good condition.
Chest Binders: Fit and Safety
How to size a chest binder
- Use a soft measuring tape and measure around the fullest part of your chest, with the tape level around your back.
- Follow the brand’s size chart, because sizing differs between companies.
- If you are between sizes, many people size up for comfort, especially when starting out. Do not size down to flatten more.
Safe wearing habits
- Wear a binder for no more than about 8 hours a day when possible, and give your body days off if you can.
- Do not sleep in a binder or exercise in one unless it is designed for that.
- Never use duct tape, plastic wrap or bandages to bind. They can restrict breathing and damage skin.
- Stop wearing it if you feel pain, shortness of breath, dizziness or numbness. Seek medical care if symptoms continue.
- Take deep breaths regularly, stretch, and stay hydrated.

Gaffs: Comfort and Safety
A gaff is an undergarment that creates a smooth, flat contour. Look for breathable, soft fabrics and flat seams.
- Choose the size that feels snug but not painful.
- Limit wear time, take breaks to rest, and avoid wearing one to sleep.
- Keep skin clean and dry to prevent irritation or infection.
- Stop if you experience pain, swelling or numbness.

Packers and Gear
Packers add shape for comfort and gender affirmation. Soft packers are made for everyday wear, while others are designed for intimacy or stand-to-pee use.
- Choose body-safe materials such as medical-grade silicone.
- Match the firmness to your use: soft for daily wear, firmer for play.
- Pick a color and size that feels right for you.

Washing and Caring for Your Gear
- Hand wash binders and gaffs in cool water with mild detergent, and avoid fabric softener.
- Do not wring them out. Press out the water gently.
- Air dry flat, away from direct heat, which can damage elastic fibers.
- Rotate between two garments, so each one has time to recover.
- Clean silicone packers with warm water and mild soap, then dry fully and store in a clean pouch.
Replace binders when the fabric stretches, loses compression or shows wear.
Comfort Tips
- Pay attention to skin. Use breathable layers, and moisturize when you are not wearing gear.
- Try on gear at home first before a long day out.
- Check in with your body regularly, and listen to what it tells you.
