Product Features
These vibrant floral-designed boxer shorts are crafted to boost daily motivation. The bouquet-inspired design celebrates the brand's 35th anniversary, expressing gratitude from BROS by WACOAL MEN to its customers. The lineup includes a special collaboration design with popular illustrator Chocomoo.
The products use environmentally conscious materials, including recycled polyester thread in the main fabric and polyurethane thread (approximately 35% content) made from materials that would otherwise be discarded during production.
The comfortable design features extra room in the front and careful consideration of seam placement at the inseam. Flat stitching at the inseam and hip areas reduces discomfort against the skin.
Each pair comes with a Hanakotoba Card featuring original flower meanings, making them perfect gifts for Valentine's Day, birthdays, and other special occasions when expressing appreciation to loved ones.

We develop materials independently according to Wacoal standards, down to each thread, until we can take pride in them. BROS by WACOAL MEN's answer continues to evolve.
