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.

No seams. No tags.
Masterpiece

High-density stretchable comfort that conforms to any shape.

The AIRism fabric used for these briefs, which is very stretchy and comfortable against the skin, is made on a warp knitting machine. The quick-drying, ultra-thin fibers absorb sweat, keeping you feeling fresh all day. The seamless design sets these apart from other undergarments.

Masterpiece

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 part of the brief. Each piece is painstakingly made on a dedicated production line built for Ultra Seamless Boxer Briefs.
