Callsign Reach gives his take on the OneTigris Zefferus Chest Rig for airsoft use... "A practical review of the OneTigris airsoft Zefferus Chest Rig by the eponymous Callsign: Reach. We take a look at wearability, maneuverability, and put this rig to the test on the field. Overall, it's low-profile, lightweight, and works well, even though it features (in our opinion) an outdated mag retention system and oversized mag pouches."
