Familiarity: I've put it through the wringer
This pack is very versatile.
Extremely light weight and absolutely no structure. Takes a little getting used to but now I use it all the time. Mostly day hikes / day climbs. Love that there are external tool loops and that my water bladder fits into the compartment where the foam back support is.
I wouldn't load it up too heavy though. I've gotten it to a point where the weight wasn't ideal for the little amount of support it provides.
Folds right down into it's own top pocket so it's great to throw into a larger overnight pack for a summit day or day hike while out in the backcountry.
