SpeedCinch system for camera safety - Cinch your camera tight against your body to prevent camera from swinging, bumping or banging around. * Lock for camera security - Lock the strap in cinched position for added camera security in crowded places or while moving around. * Bearing for mobility & stability - A greased bearing inside the attachment mechanism allows your camera to spin and rotate without unscrewing from the strap. * Fiberglass-reinforced hardware - As strong and dependable as metal parts, yet still super lightweight. * Camera Tether for peace of mind - Camera Tether provides a secondary attachment point from the strap to the camera shoulder lug.
