This Tri-Top Chest Binder by US brand Underworks offers extreme chest compression.
It has three layers of medical grade 70% nylon and 30% spandex throughout the front, and a single back layer, providing maximum comfortable and effective chest binding.
Finding the right fit is very important. Your binder needs to be tight enough that it compresses effectively, but not so tight that it causes pain or discomfort. Refer to our size guide shown in the product images or, if you are able to, we highly recommend coming in store and trying the binder on before buying. Please note, the size guide shown here is specific to the Tri-Top Chest Binder.
We recommend that you don't bind for more than 8-10 hours a day. Stop wearing it if it becomes difficult to breathe or causes any pain or discomfort.
