The Underworks Ultimate Chest Binder Tank offers extreme compression to achieve a flat chest. This style is similar to Underworks Tri-Top but this is a long 'Tank' style. This style is one of Underworks most popular binders because of its compression level.
The Ultimate Chest Binder is long enough to tuck into trousers for seamless shaping under your clothing without riding up.
If you are at the lower end of the size range or between sizes, we recommend going down one size smaller.
- Colours available: Black and White
- Compression level: Extreme

Safety Notice
Wearing a binder that is too tight for you, which causes any pain at all, could harm you. Please make sure your binder fits properly! For safety reasons although we recommend chest measurement, please also pay attention to your rib measurement, for example, if your chest measurement is a smaller size than your ribs, the larger size may be best for you to give your ribs more room to expand
