Durable, functional, fits great
Every osprey pack I own fits like a dream so that is no problem here. Tight and compact while riding, vents pretty well considering it is a backpack. Perfect amount of space for an all day ride for me, meaning, food, jacket, tools, knee and elbow pads. But when I go lighter, it snugs up nice with no dead space. Bladder has performed flawlessly for me now for a year and a half. I ride in wet and muddy conditions a ton and this thing has held up great. You can't go wrong in my mind!
