If you are set on getting a backpack, this is our top choice for comfort and organization, and we love the removable daypack! There is a stowaway harness and hip belt for added comfort when wearing the bag, but which can otherwise be kept safely tucked away and damage-free. The fabric is durable, and the zipper design allows for locks for added security (we recommend getting a TSA-compatible lock). The bag includes extra straps for a sleeping pad, though the straps can be removed if you don't plan on using them. A scratch-free pocket in the front is perfect for storing eyewear. Osprey also offers a lifetime guarantee with their packs for added peace of mind.
