Whether you're on your commute or walking across the corporate campus, the SecureTrek 15.6 Laptop Carrying Case not only protects your laptop from damage, it offers an anti-theft security system. Safeguard your bags contents by clicking the hammerhead zipper pulls into the patent-pending SecureTrek Lock Base, then add a Kensington Lock to secure it 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 organize all your stuff, and a unique pass-thru lets you strap it to a wheeled bag.
