The double sided hook design allows the shirt stay to have a strong grip on fabrics, keeping your shirt tucked in place.

Easily worn behind a standard belt, our shirt stay belt seamlessly fits with your outfit, and maintains a clean, pressed look. ADJUSTABLE – Using an entire hook and hook system, our belt offers maximum adjustability to fit a variety of waist sizes. With two adjustment straps, fitting the belt to your waist could not be easier. The addition of a 3” elastic band helps to provide flexibility throughout the day. SIZING – Available in multiple waist sizes, as well as 1” and 1.5” widths, our shirt lock belt works for either the office professional, or the law enforcement official. For jobs requiring more movement, we suggest the 1.5” width for maximum retention capabilities.
