SAVVY incorporates a patented Smart Contour Waistline™ in all of its vest products. This Smart Contour Waistline keeps the vest parallel to the gun belt to avoid the vest riding up or down the hips. In the past, manufacturers have tried to add this feature by cutting side coverage on the top or bottom of the ballistic panel. SAVVY’s approach creates a normal concave, or convex waistline, based on a woman’s shape, without decreasing ballistic coverage.
