The IRON Series is a sport swimwear line that combines athletic energy with a rugged yet refined look. The color is Smoky White, carrying a quiet, understated depth.

Because of its square-shaped form, the BOX type tends to look flatter compared to the bikini type. The IRON Series was designed to overcome that weakness, enhancing the body’s thickness and three-dimensional appearance for a more powerful silhouette.

On the front, curved lines extend from the inner thighs toward the sides. By guiding the eye outward, they create a stronger sense of volume around the thighs and highlight the presence of well-trained legs.

On the back, curves flowing along the hip line naturally emphasize the roundness and volume of the glutes. While maintaining the BOX-type shape, the design avoids a bulky look and sharply defines the body’s contours from the waist to the thighs and hips.

This swimsuit is designed with a silhouette that elegantly and neatly flatters the front, while naturally enhancing the body's lines. It aims for a refined fit and appearance with a balanced design that minimizes excess fabric.

HIGETOHACHIDORI re-examined the issues of overseas brands being too large and typical Japanese swimwear being too tight, and pursued a design that beautifully flatters the Asian body type. Our unique specifications, which consider the thigh circumference relative to the waist, aim for a natural and comfortable fit even for muscular body types.

The fabric used is a high-performance material specialized for swimwear from a Japanese manufacturer. It offers a silky smooth feel and excellent elasticity, gracefully conforming to body movements while bringing out an elegant sheen.

Double stitching is used for construction. By pressing the seam allowance in one direction, skin irritation is reduced, achieving a sewing method that balances aesthetic appeal and functionality. It offers a smooth wearing experience and high durability, resulting in a finish that can be enjoyed for a long time.

The lining uses a soft fabric that is gentle and comfortable against the skin. It reduces uncomfortable clinging and friction when wet, ensuring a comfortable feel even with prolonged wear. Furthermore, the brand logo is printed on the lining, embodying HIGETOHACHIDORI's meticulous attention to detail even in unseen areas. It is also designed to prevent transparency.

If you're unsure about sizing, please consider not only the waist but also the fit around the thighs as a guide. HIGETOHACHIDORI is designed to emphasize a balance where the front is elegant and neat, and the thigh area is comfortable to wear. It is also recommended for those who find the front rise of overseas brands too large.
