I have had two of these backpacks in the last 15 years, my first one lasting for about 12 years before it was finally time to say goodbye. I have used it for everything from short backpacking trips, to climbing days, to a school pack, and everything in between. It has a main compartment, a small mesh top pocket, an large outside pocket, two water bottle pockets, and a pocket on either side of the waist belt. With all the storage compartments, it's really easy to stay organized no matter what you're doing. Osprey really knows what they're doing and has a lot of other features too such as a helmet carry on the outside of the pack (for ski, bike, or climbing helmets), a whistle on the sternum strap (easy to blow in an emergency), a mesh back panel to offer ventilation on sweaty hikes, and an internal hydration bladder sleeve for a water reservoir to easily fit without smushing your other gear. Though it's not the most minimal pack, or the lightest pack if that's your main concern - it is absolutely great for any other kind of outdoor enthusiast, or someone looking for a versatile pack to carry on all of their adventures.
