For sale is a new, never used Deuter ACT Zero 60-10L (3660 cubic inches) backpack. This internal frame, top loader weights in at 3lbs 1oz, which is the upper limit of an ultralight pack. It has an extension sleeve that adds 10L of space. I bought it in 2010 for a trip that did happen. The pack has four external pockets: one on each side, a stretchy one on the front and a zipped pocket in the lid. There are loops for poles AND an ice axe, and lots of buckles and loops for tie-downs. This pack has Deuter's unique torso adjustment system called Vari-Quick, which can be adjusted to any length in 1 inch increments. The shoulder straps can be changed (purchased) to fit a woman's torso. I especially liked it because the pack could be raised very high to carry extremely heavy loads. The pack is well designed and has substantial padding on the shoulder straps and hip belt to carry 65 + lbs in comfort. Additional pictures are available. Asking $150 + shipping.
