As noted under the detail section of herroom.com, this bra is a 2-way cotton/spandex stretch blend which provides uniform support and breathable comfort. This garment is designed to avoid chafing. All elastic is encased for comfort and to avoid rubbing and the back straps allow for multiple adjustments and while keeping metal away from the skin.

This bra provides premium support and definition so I am surprised it did not function during certain yoga poses. You might want to try Natori Convertible Underwire Performance Sports Bra 731439. Similarly, it encapsulates the boobs controlling breast movement during light-moderate aerobic activity. Both are very comfortable with added support and control.
