Functional underwear fabrics and accessories

High elastic yarn
le Boni's special bra fabric uses a 6-ring woven structure and high-elastic yarn. It is stronger than ordinary underwear elastic fabrics and has 50% higher resilience. The fabric is smoother, more comfortable and durable.

High elastic chest pad
High elastic pad
le boni pad is 40% denser than those on the market, and its texture is firm and breathable.

Steel ring protective cover
The skin of the body is soft, so in order for the steel ring to perform its performance without causing discomfort to the body, the steel ring protective cover is very important. le Boni's proprietary 7-layer overlapping steel rim protective cover has a structure that is more comfortable to wear than the general 4-layer design, without feeling any pressure.

Composite air cushion soft stick
Composite air cushion soft sticks have many uses, but they are most familiar to women and are placed under the armpits on the left and right sides of the bra to prevent chest fat from flowing to the armpits and causing thick back muscles and thick arms.
The composite air cushion soft rod is used in high-quality underwear in Japan. Its design feature is that it is developed with two layers of hollow resin. The two layers of resin are relatively strong. The air flow air cushion design with an open middle makes it comfortable to wear.

Steel ring
The le Boni steel ring is more comfortable than the general cylindrical steel ring, and its flat performance is more integrated between the breast and sternum.

Shoulder strap
The thickness of the shoulder straps, the width of the back buckle and the supporting capacity of the breast cup are related. The ratio of the thickness of the shoulder straps to the width of the back buckle should be no less than 0.5 inches, so that the shoulder straps can provide mechanical support and enhance the chest.
The length of the shoulder straps must also meet the size standards. The shoulder straps should be placed evenly at the top of both shoulders and have a finger-level tightness to make the shoulders comfortable.
Underwear fabrics are carefully selected from Japan

Cotton

Microfiber
