Umates TopBackPack Partno.: 10-008 Do you have a laptop with a screen size up to 17"? If you want both hands free when carrying your laptop, Umates TopBackpack is the ideal solution. The Backpack with its classic good looks is unique in that it is designed specifically with your laptop in mind. The Backpack has been designed with lots of practical details. Of course, it comes with the Umates elastic sling system - TopProtector™ - which protects the computer against knocks and bumps. The elastic sling system is detachable, so you can use the Backpack even when you don't need to take your laptop with you. A heavily loaded backpack can be hard on your back – so we use softly padded shoulder straps and a padded backrest to protect you from any discomfort
