Underworks Cotton-Lined Binder

Color: White

This cotton-lined chest binder flattens the chest using two high-compression layers in front. It has a single back layer. The inner cotton lining is softer than the outer lining, so many people find this type more comfortable than unlined binders, although it may be warmer to wear. It also has a unique cut that can allow for greater arm movement. This binder stops at the mid-belly on most people. Your binder will stretch out a bit; be sure to follow the sizing guide for best fit.

Care Instructions

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


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.

The Tri-Top Binder is 14.5"to 16.5" long, depending on which size you order.
