When you need to haul in a lot of gear, the last thing you want is to have to make more than one trip. That's when you need the Outfitter Expedition. The largest of all our packs, the Expedition comes in at 8200 in³ fully extended and with all the features to carry such a load. The contoured shoulder straps are padded, adjustable and come standard with sternum cinch to hold the pack tightly, while the padded waist belt assists in distributing the load along those long hikes. The top gusset adds another 9.5" and allows for a little extra room, covered generously by the top flap to keep your things protected from the elements.
