Gregory Optic 48 L Backpack in mens medium.  This pack has only been used a few times and is in excellent condition, with no stains, tears, holes, etc.  Gregory classifies this as ultralight: the weight with brain is 2.47 pounds, removing the brain and installing the top flap reduces weight to 2.37 lb.  The rain cover weighs 0.21 lbs.  The medium Optic fits a torso range of 18 – 20 inches.
