Evisu has spent the last 10 years developing their jeans to be as authentic as today's vintage jeans can be. All Evisu jeans are made of vintage selvedge denim. This means that the denim is made on old style shuttle looms rather than modern projectile looms. In simple terms this means that the cross thread in the weaving process goes back and forth during the weaving process. But modern looms, shoot each cross thread through individually, hence the edge of the cloth is frayed rather than clean (although brands who are only interested in making quick money, try to cash in by faking the smooth selvedge by stitching up the frayed edge afterwards).
