This is a great bag. It served me well. The separate pouch for your computer is great! :D Below is the company's description of this bag. :)

"Timbuk2 has set the mark for bags whose form and function flawlessly combine for flavor and flair. Their computer bag "the Blogger" is versatile enough to hike the Rockies, stroll a college campus or climb the corporate ladder.

The Blogger is a vertical shoulder bag featuring ballistic nylon exterior. Ballistic fabric has a higher sheen, brighter colors, and a smoother surface which won't rub your clothes the wrong way. It's even water and stain resistant for those days life catches up to you.

Two spacious exterior pockets and rubberized bottom keep your goods protected at all times, while the padded shoulder strap adds comfort and convenience. Classic Timbuk2 three-panel design and a built-in plush corduroy laptop compartment (fits 15" laptop) round out the Blogger's resume.
