So many pockets! This backpack has 3 main compartments with corresponding zippers. Watch the video! It also has a side zippered water bottle holder and a spot at the top near your neck to hold something small. Each compartment comes with additional pockets and zippers. There is also a computer compartment with a Velcro strap to keep your computer in place. An excellent backpack for travel, work, or school. I ship all items on the next business day. Feel free to always make me an offer! Let me know if you have questions.
