The holster is designed to keep a low profile, simulating the natural way to carry a weapon inside the waist band without any holster at all. The holster is built from a flexible back that buffers between pistol & body, a non-collapsing shell that covers the pistol, and two belt clips to position the holster at waistband height. The holster is lightweight, fully tuckable, completely washable, ventilated, durable and comfortable, and most important, it is a universal IWB holster, designed to accommodate multiple same-sized pistols, and therefore requires no shell replacements when changing between pistols of the same size.
