Product Stories
No seams. No tags.
These boxer briefs are made up of five parts, but without seams or hems. Made from high-density stretch fabric, which stretches 360°and returns to its original shape, these boxers are made without using threads, creating a seamless, wrap-around feel.
Comfort that moves with you.
Crafted from our innovative high-density "AIRism", this underwear offers exceptional stretch and comfort against the skin. Produced on a warp-knitting machine, the ultra-thin fibers provide effective sweat absorption and quick-drying, alleviating the stuffiness often associated with traditional underwear. The seamless, dense fabric fits gently against your body, distinguishing it from other undergarments.
Boxer briefs made without using a single stitch.
These boxer briefs are made without stitching by bonding fabrics with a special resin. It may sound simple, but the process is more labor-intensive and delicate than sewing with thread. The resin's amount and density must be precisely calculated, some processes must be done by hand, and the temperature of crimping and cooling must be carefully controlled for parts of the brief. Each piece is painstakingly made on a dedicated production line built for Ultra Seamless Boxer Briefs.
