This binder inner supports ease of movement while minimizing breast bounce and visibility. It's a comfortable, close-fitting inner that's easy to use for both sports and daily wear.

For those concerned about breast movement during sports. For those who want to minimize breast visibility and move freely. For those looking for a bust support innerwear that isn't too constrictive. For those who want to be active in club activities, exercise, work, school, and daily life. For those who prioritize a comfortable fit.

Designed to hold the entire bust flat, it suppresses movement and protrusion, and supports ease of movement. It creates a state where you are less bothered by bust movement or stares during sports or daily life, making it easier to concentrate on your body's movements.

Its unique flat pad structure and soft material are designed to provide a natural fit while reducing pressure. This bust support innerwear is designed to not hinder breathing or movement, making it comfortable for extended wear. A joint study conducted by OPT with Professor Kazuhiro Hirose of Waseda University confirmed that the flat pad structure maintains high holding power while having an impact on maximal exhalation (the force of exhaling) equivalent to that of general sports bras with cups. We pursue the concept of "unrestricted comfort with excellent support" based on our unique evidence. It is available in black and white, and in sizes Small, Regular, and Large.
