This was the very first backpack I purchased when I learned about hiking gear and had an idea of what I needed to fit my specific needs. This pack has been with me all over the world and around the country and I love it! It is comfortable to wear for long periods, even when I have it packed completely to the brim! There are mesh pockets on the sides for extra storage and the mesh pocket in the front is a lifesaver for quick access. My favorite features are the zippered pockets on the waistband for my phone and chapstick/essentials and the bladder compartment is OUTSIDE the backpack so you have easy access to it anytime you need to fill or remove it.
I was so happy with this that I purchased a smaller Osprey brand backpack for my shorter hikes too!
