Good around town, good on the trail
This back-pack is a great size for my daily half-hour walks to and from the office. I've also brought it on a few short day hikes.
I toss it on the floor of my office every day and then on the floor of my home every night and I've seen nothing so far that makes me doubt it has all the legendary Patagonia durability that I've come to expect.
It may be a little bigger than the average day pack, but I don't find it awkward at all when it's not full. It adjusts nicely when mostly empty and then expands perfectly when full. I love the fact that the laptop pocket doesn't go all the way to the bottom of the backpack because that gives added protection to my laptop when I throw (er...I mean "place") my backpack on the floor.
Zippers seem very well made and I don't find them difficult to work with. Love the side pockets. Inner pocket holds a hydration bladder perfectly.
Overall a well designed, sturdy backpack. If it starts to show wear and tear or I find any flaws I'll be back to update you.
