A combination of timeless fashion and durability makes STM laptop bags and cases the best bet. Check out this STM laptop backback made for 15-inch laptops, and much more gear.

1st Compartment: For Gear and Protection Devices
This laptop backpack offers two independent compartments, one for your gear, and one for your laptop. The compartment for your gear is designed to hold books, power adapters, PDAs, phones, cameras, small camcorders, art utensils, and simultaneously protects your most expensive mobile asset: your notebook. For extra protections, a slim shell that goes up and down, velcros onto the inner flap of the first independent compartment to ensure protection for your laptop in case of drops or other stressful environmental factors and gravity-oriented occurrences.
2nd Compartment: For Your Notebook/Laptop
This compartment is simple; it has no pockets or zippers to scratch your laptop, just a slick poly-material that encases all four inner walls of the main compartment, which are made of thick lightweight padding: a similar padding that you find in the soles of thick rubber sandals. This level of protection will ease your mind as soon as the laptop enters the bag. You will be able to bang it up against the wall accidentally, toss it into the backseat of your car, slide it across the hardwood floor in your living room.
Appearance
The bag is made of a tough water-resistant material that is black and grey with blue trim. It includes a tiny little part for your iPod/MP3 player cable to string through so you can keep your player safe and dry and still listen on your headphones. No matter what devices you carry around, this bag is especially made for it. The dye used on the bag will stay looking good through years of all weather.
