Always use your actual body measurements rather than bra or clothing sizes. Measure your chest circumference at its fullest point, then refer to our Size Guide.
If you’re between sizes:
- Choose a smaller size for a firmer fit in our Regular Binders.
- Consider a larger size for our GYM Binders due to their stronger compression.

To find your ideal chest binder size, you’ll need a soft measuring tape. Wrap it around the fullest part of your chest — usually across the nipples — and make sure it’s snug but not too tight. Keep the tape horizontal across your back and chest for accuracy. For best results, measure without a bra, sports bra, or binder.
No — bra sizes and chest binder sizes are not the same. Bras are designed to lift and support using cup and band sizes, while chest binders are engineered to smooth and flatten using your actual chest measurements. Using your bra size can lead to the wrong fit — too loose or too tight. For the best fit and most comfortable compression, always measure your chest circumference and check our Size Guide.
GYM Binders are designed for light to moderate workouts. They offer stronger compression with a tighter fit. They feature a racerback cut and larger armholes, providing greater shoulder mobility — especially helpful for people with broader shoulders. This design helps minimize chest movement, making it ideal for workouts, sports, and other physical activities.
Yes — many people choose our chest binder because it offers a balance between support and comfort that they can’t find in traditional sports bras. If you find sports bras lack the smoothing effect you want, but feel typical binders are too restrictive, our design is for you. For active days or everyday wear, it’s a supportive option that feels both secure and empowering — without compromising your ability to move freely.
Absolutely. Our chest binders are made with high-stretch LYCRA® fabric that’s built for movement and comfort during physical activity. Whether you’re doing cardio, yoga, strength training, or stretching, the flexible structure provides a secure fit without restricting your range of motion.
The key to comfort and performance is finding the right size. Everybody is different — and sometimes, the best way to know what feels right is simply to try it on and see how it moves with you.
No — we advise against sleeping in any compression top. Even with our soft, breathable materials, your body needs time without compression. Please remove the chest binder before bed to allow your body to fully rest and relax.
Our Regular Chest Binder is available up to size 8XL, and the GYM Chest Binder goes up to 6XL — covering a wide range of chest sizes and body types. These extended sizes are designed to accommodate most people looking for effective smoothing and support.
However, we know that sizing isn’t one-size-fits-all. If you’re unsure whether our largest size will work for you — or if you’ve tried it and it doesn’t feel right — please email us your chest measurements. Our team is happy to offer personalized sizing advice to help you find a fit that feels secure, comfortable, and confident.
To maintain shape and compression:
- Hand wash with cold or warm water and mild detergent (recommended).
- If machine washing, use a gentle cycle with a laundry bag.
- Always air dry to preserve elasticity. If you must use a dryer, choose the lowest heat (under 60°C / 140°F) and limit to 45 minutes.
