Mobile Edge SecurePack 17" Backpack White Camoflage/Orange

Excellent construction, nice looks, well-designed. It even holds my Sony 18.4" VAIO AW but it requires some strain to get the zippers to close so I wouldn't recommend it to carry computers larger than 17" screen size. It'll surely hold any other laptop quite well.

The security feature of the zippers placed under the shoulder straps towards your back will prevent anyone from stealing anything while you're in a crowded place like a subway train. The case includes two well-sized zippered removable pouches for a power supply and other accessories, four small internal compartments (three stretch neoprene with velcro fasteners and one mesh), and a separate compartment for an MP3 player or whatever with a slit opening for your headphones cable.

One small concern is that the computer compartment is located on the end that faces the wearer, hence your back is always pressing against the computer. Placing the computer with the bottom end (instead of the screen) facing your back will remove the strain from the screen, but depending on how much additional stuff you carry, the rest of the contents will be pressing against the screen, so...

If you're a professional who wants to be able to carry your computer without the usual fuss of handling a shoulder strap to keep it from slipping, or if (like me) you usually carry your computer everywhere and want to be able to move your arms and hands freely, this bag's for you.

If you're a student who --in addition to your computer-- needs to carry a lot of books, consider something else before you make your purchase as this backpack might not be the most spacious for your needs.Buy Mobile Edge SecurePack 17" Backpack White Camoflage/Orange!
