I like the concept , they are very comfortable , and ride tight to the body .
That said , I don't get along well with them , they take up way too much belt space . I had a CRK Aviator for several years , should have hung on to it . They are also quite concealable , and don't "print "thru jackets and cover garments as much as other types . From a leather worker's standpoint , they take up a lot of material , and are labor intensive - ergo expensive .
