The size is way smeller than the chart showing. I would recommend  your to order 2 size up at least. The quality is pretty good but not soft- a kind of hard. The refund service is pretty good. You only need to bring it to any Walmart store near you to return.

Size

It fits well and hasn't stretched out much despite almost daily wear. Doesn't produce as flat of a chest as I was hoping for, but does a way better job than anything I've tried before so i consider it a win.

Tri top binder for trans men

Underworks Tri-top Chest Binder in black, shown on a model. This mid-tummy length compression binder is made from 70% nylon and 30% spandex, featuring three layers of compression on the front and a single layer on the back for comfort and support. Designed for chest flattening, it is suitable for individuals with gynecomastia, transitioning, or requiring additional support during physical activities. The binder is seamless, undetectable under clothing, and crafted in the USA for durability.
