Familiarity: I've put it through the wringer
I've used this pack for summer rock cragging, long alpine days, and winter ice climbing. I can stuff a large summer trad rack, plenty of water, harness, food, jacket, etc. in this pack. It also rides comfortably when carrying, fully loaded or lightly packed on a multipitch route. The gear loops are fantastic! It also has a nice variety of small inner zip pockets for small items. Can't say it enough. Love this pack!
