The "Cooper" is a purpose built appendix rig made from the same great material we use on all of our products, BOLTARON. Two tuck-able belt clips ensure stability and consistency. Included with every Cooper holster is a concealment claw to aid in tucking the grip of the gun further for better concealment. The claw is adjustable by moving it backwards or forwards, you can also choose to remove it.
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.
