The Pack Rat is a Holster designed for use in concealment packs. It utilizes velcro on the back side instead of a belt attachment making it perfect for bags such as vertx or any Loop velcro you have applied.
Kydex is almost an industry standard for gun holsters, but at Kerber Arms we've chosen to go beyond the standard and use Boltaron for all of our holsters. The material Boltaron rivals Kydex in tensile strength. Boltaron can withstand higher temperatures than Kydex before deforming in high heat or cracking in extreme cold. While already matching or beating the best competitive materials in stress and fractures, Boltaron has shown great promise for use in all fields.
