An X-Port Expandable Portfolio is a top-loading art carrying case that opens across the top with a secure hook-and-loop flap instead of a zipper, and expands to a six-inch gusset — roughly twice the load of a typical 3-inch zippered portfolio. The listed size is the usable interior flat dimension, so a 20"×26" case actually holds 20"×26" work. Framed artwork, print boxes, mounted boards, and mixed-thickness loads slide straight in from the top instead of being wrestled through a side opening.
The line comes in two builds. The four standard sizes (12"×16" through 23"×31") carry like a traditional portfolio: a leatherette handgrip, a business card window, two stretch interior pockets for accessories, and a body that collapses flat for storage. The four oversized sizes (25"×37" through 41"×61") are engineered for large-format work: two vertically spaced front handles let you carry with the bottom of the case elevated at whatever height clears the ground, and end-panel zippers convert the case to clamshell mode — the whole front opens like a lid for flat loading or flipping through prints in place. The oversized cases hold up to 24 foam boards in the six-inch gusset and add two gusseted outside pockets and an ID card holder.
Every size is made from tear-proof, water-resistant 600-denier polyester, includes a detachable shoulder strap with all-metal hardware, and is covered by a two-year warranty.
