Even though it looks like a standard messenger-style laptop case, the $119 Pacsafe CourierSafe 100 packs a wealth of hidden security features into its unassuming frame. After all, it makes sense that a bag containing your valuable laptop, and potentially even more valuable data, should have some fairly robust security, and that's the mentality behind the Pacsafe line of cases, which all incorporate features such as slash-proof shoulder straps and tamper-proof zippers.
The CourierSafe 100 additionally offers a mini combination lock for anchoring the strap around a fixed object or locking the zippers closed, on top of the standard Pacsafe defenses against knives and box cutters. It's also a reasonably attractive, comfortable laptop bag that's bulkier than its saddlebag cousin, the Pacsafe MetroSafe 300, but has roomier, therefore more usable, pockets inside.
At 16.5 inches wide by 13 inches high by 6.5 inches deep, the Pacsafe CourierSafe 100 can hold a 15-inch laptop, and even a bigger one, such as the Toshiba Qosmio F45. The case is made from basic ballistic nylon, and the main laptop compartment has metal wires woven inside the material, which Pacsafe calls an eXomesh slash-guard panel. That's to keep someone from using a sharp knife to slice open your bag and snag your laptop. The shoulder strap is likewise reinforced with slash-proof, high-tensile stainless steel wire, to stop blade-wielding thieves.
A small combination lock sits at one end of the shoulder strap. The lock can be used to anchor the strap around a table leg, light post, or other secure object, and it includes a metal loop for threading through the zipper pullers to keep the bag closed.
