The Underworks Tri-top Chest Binder has three powerful layers of medical industry grade 70% nylon and 30% spandex throughout the front, and a single back layer, providing maximum chest binding. Does not cover the lower belly area.

Made in the U.S.A. High quality construction.

Style number 983. We have decided to give names to the different Underworks binder styles to help our customers tell them apart. We call style 983 "Floyd." 

White. Comes in 7 sizes: XS thru 3XL. Sizing, care, and measurement recommendations below.

How to measure
First, take a snug measurement under the breast line with a soft tape measure-- lift your breast tissue up and place tape underneath if necessary (this is a measurement of your rib cage). Next, take another measurement over the fullest part of your chest. You might want to wear a sports bra when you do this. Again not too tight but not too loose. Take the average of these two measurements and apply the result to the sizing recommendation provided below.

EXAMPLE OF HOW TO FIGURE AN "AVERAGE MEASUREMENT"
If your measurement of the rib cage is 32", and the over-tissue measurement is 38":
32" + 38" = 70". 70" divided by 2 = 35".
In this example, you'd use the average measurement of 35" to find the correct size.

If you are between sizes (unless you’ve already tried this binder and know your size), it is likely better to opt for the larger size, since compression garments are already designed to fit snugly.

Each Underworks item has a different scale based on the elasticity of the fabric used and the cut of the garment, so please pay attention to the sizing scale for each style.

XS: 28" to 30"
Small: 31" to 33"
Medium: 34" to 36"
Large: 37" to 40"
XL: 41" to 44"
2XL: 45" to 48"
3XL: 49" to 52"

Care For Your Binder: Hand wash or machine wash your binders ONLY in cold water. Use gentle cycle when machine washing. DO NOT iron. Do not place the garment near any kind of heat source. DO NOT use any kind of bleach. Drip dry or flat dry, DO NOT place your binder in the dryer.

How To Put On Your Binder: Tank top style binders are slipped on just like a pullover or a t-shirt. In some cases, depending on your body type, if a binder is too difficult to get on this way, simply step into the garment and pull it up.
