A golf backpack, having a main body with a front side and a back side substantially opposite each other, and which is attachable to the shoulders of a user by a pair of straps on the back side, and an internal structure arranged inside the main body. The backpack has a support structure arranged on outside the main body, on the front side and fixed to the internal structure, having this support structure fastenings for the balanced positioning of golf sticks arranged in use of the backpack in a plane parallel to the back side of the main body and symmetrically with respect to a vertical Z axis.

The present invention discloses a soccer training ball with an outer covering of ball that consists of a plurality of panels disposed between two opposing apex panels. The plurality of panels encircles the spherical ball each panel substantially extending the diameter of the spherical ball between the outer peripheral edge of the pair of opposing apex panels. The opposing apex members are preferably polygonal shape.

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.
