There's a lot to say about a holster's position - both on the gun owner's waistline and in their lifestyle. The ShapeShift AIWB holster was made in America to be a comfortable, concealable, customizable mode of appendix carry holster that adapts as much to the concealed carrier's draw style as it does to their body. It's a modular holster. The Shift Shell may be uninstalled from the backer and mounted to any of the other ShapeShift carry options. This inside the waistband appendix holster may be a classic IWB, OWB belt slide or an OWB paddle holster within a moment's notice. The ShapeShift modular holster requires zero tools. The AIWB holster backer was designed for both the handgun and the carrier. Alien Gear chose four specific materials for their performance factors. A perforated neoprene rests against the body, wicking sweat away from the handgun and ventilating the entire holster backer. A resilient thermo elastomer material sits on the front for durability and retention. Beneath the neoprene and thermo elastomer is a core composed of two materials. A layer of flexible, tough spring steel and a layer of strong ballistic nylon lend strength and reliability within the holster backer. The low-profile Shift Shell was also designed for strength. It is made from injection-molded polymer, shaped to the lines and contours of the handgun model. All the parts and clips are also made of that polymer. Additional Shift Shells may be purchased so that multiple types of compatible handguns can be carried on the same holster system. An adjustable retention unit may be installed for the preferred level of passive retention. This innovative holster was made in America by gun owners for gun owners.
