Abstract: Disclosed is a holster for concealment inside a waistband of a lower garment of a user. The holster includes a support sheet having first and second surfaces and made of at least first and second layers of different material. The first layer comprises a pliable leather material and the second layer comprises a resilient elastomeric cushion material. The second layer is positioned inward toward the user relative to the first layer when the holster is in use.
