Whether on your commute or heading to an off-site meeting, the SecureTrek 15.6” Laptop Backpack not only protects your laptop from damage, it offers an anti-theft security system. Safeguard your backpack’s 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 luggage 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 organise all your stuff, a padded back for extra comfort, and a unique pass-thru lets you strap it to a wheeled bag.
