Described herein is a golf bag with a collapsible pocket assembly. The golf bag can comprise a first pocket, a second pocket, and a third pocket, wherein the third pocket comprises a wall. The third pocket wall can comprise a first region and a second region, wherein the first region of the third pocket wall is the same wall as at least one of the sidewalls of the second pocket. When shipping golf bags, the golf bag flats oftentimes must be shipped separately from the golf bag tops. The instant golf bag can be collapsed for shipping, allowing the golf bag tops to be partially installed onto the golf bag flats prior to shipping, reducing shipping and assembly labor costs.
