When you're traveling for business, the SecureTrek 17 Laptop Overnight Backpack not only protects your laptop from damage, it offers an anti-theft security system. Safeguard your backpacks contents by clicking the hammerhead zipper pulls into the patent-pending SecureTrek Lock Base, then add a Kensington Lock to secure the backpack to a fixed object. Or you can use a TSA-approved laptop lock when flying. Protected by durable Poly Twill material, your laptop and tablet stow in padded compartments and are shielded by an anti-puncture zipper. There's ample space to organize all your stuff, including clothing for an overnight trip, a padded back for extra comfort, and a unique pass-thru that lets you strap it to a wheeled bag.
