Note: This listing is for the POWDER BLUE color. This backpack is gently used and in good condition. It is a super roomy backpack, good for day hiking, traveling, or general everyday use! We upgraded to bigger backpacks and no longer had the room to keep. The pack has a slot and carry area for a hydration reservoir and has an attached rain cover in a dedicated zippered storage area in the bottom. It also has expandable side pockets for bottles and an easy access and part-mesh front slip pocket. There are three easy access main compartments of the backpack. The smallest contains 3 mesh organization pockets for small items and a hook for keys. The medium is roomy and does not have any additional pockets. The large contains a pocket for your water reservoir or even a laptop when a reservoir is not in use. The straps are thick, sturdy, and comfortable.
