This backpack is light, weighing in at just over two pounds.  I was looking for something for fast, light climbs, or overnight hikes.  Thinking about the Matterhorn next year.  It has one of the largest volumes for the weight and it is remarkably sturdy.  It doesn’t interfere with a climbing helmet and the abundant compression straps keep it close to your body for bigger wall climb.  There is an internal frame but it is not hydration compatible.  I really love this pack, I’m not giving it 5 stars because I wish there were a few more pockets, perhaps on the side, or the belt or the shoulder strap etc.  Acter’yx maybe left these out save on weight, but a few more places to stash stuff besides the lid would make this pack even better.  I got the pack from Steep and Cheap, one of my new favorite places to find outdoor gear.IMG_0873
