The inner-tailored waistband of pants is the finish given to pants inside. There are differing levels of quality: from pre-produced to personalised, or even fully hand made for each garment.
Messori uses a high-quality personalised inner-waistband which also has an interesting innovative touch: a narrow rubber strip has been incorporated into the edge of the waistband to prevent shirts from slipping out of the pants, especially due to movement.
