This pack has been used on less than a dozen short backpacking trips and is in Good Used Condition. There are a few small stains which are shown in the photos, and the internal portion of the waist belt buckle is a bit chewed (by my puppy). In addition to the spacious main compartment (double drawstring closure), there are 2 mesh drawstring pockets on the sides of the pack, 2 lower elasticized mesh pockets, and the top lid (which also has a small inner pocket and a key leash). The main compartment can also be quickly accessed with a convenient u-shaped zipper on the front of the pack Volume 3500 cu in (57 liters) Weight 3.3 lbs 22" x 16" x 34" (56 x 41 x 86 cm) Materials Dyneema gridstop Here is what Backpacker Magazine wrote about it: It’s no secret that this pack is light, affordable, packed with bells and whistles, and big enough to hold 4 days’ gear.
