Fabrics for boxer briefs are stretch, for example, cotton combined with elastane, and the blend of modal (natural fibers) and elastane. Generally, pure cotton is the best fabric for breathability.
The waistband is usually an elastic band. The bonding technology (with a little suture) is adopted by underwear factories, as it ensures comfort. The fine workmanship requires experienced laborers. Therefore, the cost is not low.
Men’s Boxer Briefs with U-Shaped Pouch is highly welcomed today. The pouch is made of breathable silk, so the price is higher than ordinary boxer briefs.
