The Super Duffel measures 29" long x 10" high x 12" deep, and is divided into 3 sections. The center section (22" long) has a large 3-sided opening with a generous storm flap covering the zipper. Compartments on the ends (each 3.5" long), each have their own zippers, and one has a hidden security pocket. There are six D-rings, four to use as bungee anchors and two more for an optional shoulder strap. This duffel swallows a huge amount of stuff and works well in almost any travel scenario, though our GS riders seem to love it most!
