While the description of this pack says it will fit a laptop, I bought it not knowing if it would have a pocket for one... I was very pleased when I saw that it indeed has a padded pocket that perfectly fits my 15" laptop.
I've also been in the rain with this backpack and the water simply beaded-up on it and no signs of anything wet inside... so can definitely vouch for it being water-resistant.
Overall - the perfect size backpack for everything I need in my workday.
For me, an average sized man, this is my ideal pack. It's not too big and bulky and not too small. Fits everything I need on my outdoor explorations and has the durability that I need. Also the mesh backing lets my back breath. Perfect. I bought another one for my brother for Christmas.
