Care Instructions

Wash in cold water on the gentle cycle. Hang or lay flat to dry, do not put in the dryer. Do not bleach or iron.


Please note the Ultimate binder fits about one size larger than the Tri-Top. For example, if you take XL in the Tri-top your size will most likely be Large for this binder.

To find your size, take a snug measurement around your ribcage with a measuring tape. Next, take another measurement over the fullest part of your chest. Take the average of these two measurements and apply the result to the scale provided below. Make sure to keep the measuring tape snug, and parallel to the floor to get the best measurement. Your binder will stretch out a bit; be sure to follow the sizing guide for best fit.

The Ultimate Chest Binder is 24"-28"long, depending on the size you order.
