Good size, not too big or small, lots of compartments and keeps everything organized.
It feels so good on my back and is lighter than the smaller back pack that I used to use. This is perfect for me.
The layout and pockets are great. Zippers all seem to work great. All for a very low price.
It holds everything I need very comfortably and professionally. When used to travel, it expands to hold your extra items. The straps and back are very cushioned and make the backpack feel lightweight even when fully packed.
