Wesol's Shirt Lock is made of a flexible, hook-on-hook material that is worn over your shirt and inside your pants, about two inches below your waistline. The belt grips both the shirt and the pants, holding your shirt tails down and your pants up. Shirt Lock is a newer version of the Sticky Belt and is a great alternative to shirt stays. The 1.5-inch width provides extra support for officers wearing a duty belt. Alternative sizes and non-metallic "airport friendly" versions are available. Made in the USA.
