The perfect outfit starts with the right base layer—that means a top-notch pair of boxer briefs. This pair from Line of Trade has all the right ingredients: a lay-flat waistband, antimicrobial bamboo viscose fabric, legs that stay put, and a pouch-shaped, contoured crotch panel that keeps everything where you want it. They look good when the pants come off, too, with contrast stitching and classic shades chosen to suit a variety of skin tones.
