Interesting chest rig at SO Tech... "S.O. Tech developed the internal magazine slot system (patent pending) to drop the six rifle magazines into the flat panel that makes up the body of the Falcon. The internal magazines slots lay the six magazines f­lat against the soldier’s waist, reducing high chest profile. Allows soldiers to lay flat & closer to the ground. Internal Hydration harne­ss system on back allows additional pouches to be added to the back on PALS webbing sewn to outer face of hydration carrier. Allows more space to attach mission specific pouches."
