Familiarity: I've used it several times
So I picked this pack up just a few weeks ago and I have already taken it on several trips. This pack has just enough room for just about anything you want to throw at it. I can get all my sport climbing gear with rope and snacks and water in it which is great. I also recently took it up Longs Peak and packed all my overnight needs, tent and all inside it, along with my hiking needs for the climb up Longs. It is about to go to Yellowstone this weekend for use as a day pack. I love that it can expand or shrink as needed for the activity and doesn't flop around when there isn't much in it.
The support is great and this packs all the features of a full blown backpacking pack in a small and light package. This pack will see a lot of miles.
