A pocket device including a first major panel and a second major panel coupled together along a major fold line. The pocket device further includes a first pocket panel coupled to the first major panel along a first pocket fold line and forming a first pocket with the first major panel, and a second pocket panel coupled to the second major panel along a second pocket fold line and forming a second pocket with the second major panel. The first and second pocket panels are coupled along a minor fold line. A reinforcing material is positioned on at least part of at least one of the major fold line, the first pocket fold line, the second pocket fold line or the minor fold line.

A system including a panel having a panel opening and a coupling device coupled to the panel. The coupling device includes a coupling device opening and a flange positioned adjacent to the coupling device opening. The coupling device opening at least partially overlaps with the panel opening, and the flange is elastically deflectable to allow a binding mechanism to pass the flange and into or out of the coupling device opening.

The foldable holder includes a first panel, a second panel, a third panel, a shroud, and a retractable closure. The foldable holder is foldable between a closed configuration in which the panels are stacked and an open configuration in which the panels are substantially coplanar with one another. The shroud attaches to the second panel to define a shroud passage between the second panel and the shroud. The retractable closure is moveable between a secured state in which the retractable closure is engaged with the first panel to retain the closure in the closed configuration and a retracted state. The retractable closure comprises an elastic retraction member to urge the retractable closure towards the retracted state and a closure tab engaged with the engagement surface in the secured state. The closure tab is at least partially disposed within the shroud passage in the retracted state.

An exemplary embodiment of the present invention provides an improved yardage book holder for storing a yardage book as well as a variety of other golf accessories. The yardage book holder comprises a substantially slender thickness and a rectangular profile with rounded corners that allows a golfer to conveniently store the yardage book holder within a pocket in an article of clothing when folded in its fully closed position. The yardage book holder further comprises at least two layers of materials, a plurality of sections, a plurality of compartments, and a strap affixed to one of the sides of the yardage book holder. The strap allows for quick access to the item which it secures and is able to pivot such that it may quickly attach to or detach from the interior or exterior surfaces of the yardage book.
