The FasTrax PAC uses a combination of a pivoting holster component and external activation cord. This enables you to get your handgun into action much faster. To maximize wearer comfort, the FasTrax PACs back panel is made of Galco's Comfort Cloth, an Adaptive Performance Mesh that provides padding and moisture wicking with an adjustable, stretchable elasticized waist strap and a Nexus buckle for quick on-off capability. Adjustable 1.5" wide waist strap (up to 50").
