Four ( 4 ) single pistol mag pouches with velcro loops and buckle, fits belts/backpack straps/boots (crazy I know)/camelback straps, streamline with belts for smooth use and the buckles hold very well while running and jumping. Handles almost every pistol mag I’ve tried in them aside from rifles obviously, has adjustable velcro for the buckle to allow larger/extended pistol mags if needed. Light use but in good condition.
