Very confortable back pack with nice yellow glare stripes for the night ride on a motorcycle. Also it is cool and a good air flow while riding the Motorcycle.I bought this to use it when I ride my Motorcycle. It is comfortable and I think it is a good size for my 17 inch laptop.For my accessories of my laptop, I had to use the inside zipper packet to put my laptop cord but it is not designed for that.Also, the description of this backpack, stays that has front packets for your cell phone, but I could not put my G4 LG in there cause the packet is to small, way to small not even a regular new style phone will fit in there. Also no bottle water packets and last but not least, the way to put the laptop in you have to fold back the straps to be able to slide it in. Overall I will give it a 4.5
