Modular podular, dude. Use these zip-opening squarish bags to organize your packing job into sub-categories for quick retrieval. Made of nylon packcloth with a full-length zipper along the top that makes access easy. The blocky shapes lend themselves to compactness when placed in saddlebags (which tend to be rectilinear) making the best use of that always limited space. Perfectly suited for separating clothing from cookgear and the like. Simple and quite handy to stuff your stuff in. Assorted colors. Sold individually, four sizes to choose from. Small: 7" x 11" x 8" Medium: 8" x 13" x 7.5" Large: 8" x 15" x 9" XLarge: 9" x 17" x 10"
