The big boy. When you need more gear than will fit in a "normal" wedge the A.T. Expandable is the way to go. Made of Dupont Cordura? and supported by a HDPE shell like the smaller A.T., you are guaranteed a stable blowout free ride. The beauty of the A.T. Expandable is that when you need more room just zip open the expansion sleeve and you increase the volume by over 40%. That's enough space to shed extra clothing or pack 8 more energy bars (better bring lots of water).
