The guys at Parabellum use Reservation Bison, which is the richest, softest, most complicated and most beautiful leather in the world. It is tanned in small batches, using old world techniques by true American Artisans. They use natural-tone; vegetable tanned Lamb Skin Linings to compliment the rugged beauty of the Bison. All of their leather goods are internally lined with Kevlar for strength and durability. And, each and every Parabellum product includes laser-etched, Military Grade Ceramic hardware to perfectly contrast the leather, and to set their products on a level of true technological sophistication.
