The Ghost 20 is a hybrid pack suitable for a backpack, briefcase, or messenger bag. Although built to accommodate a laptop, books, documents, and other essentials of everyday work life, the heart of the Ghost 20 has an integrated back panel pocket intended to secure a handgun for EDC/CCW practitioners. An ambidextrous, zippered pocket in the back panel is lined with a material that works with common hook-and-loop style holsters, allowing the user to securely stow their defensive handgun discretely and within easy reach. The bag's main compartment panel is similarly lined with hook-and-loop material, providing users with an alternative location for stowing a holstered gun or spare magazines.
