At the core of the Eidolon is the holster shell. The shell is precisely fitted to the weapon on the inside and is smooth on the outside to work in conjunction with the body, belt, and clothing -in nearly any carry position- to maximize comfort and concealment. At the same time, the shell provides attachment points for a host of accessories to allow the user to tailor the holster for their specific carry needs. 1.5" belt loop. Mfg: Raven Concealment Systems
