About This

• TRAVEL READY: This handy travel set combines Knack's popular expandable Series 1 Medium laptop backpack with our best-selling expandable/compressible Packing Insert and insulated, stainless steel water bottle to create a must-have travel set that's big on convenience and organization.
• UNMATCHED FLEXIBILITY: We designed Knack backpacks to let you live your best One Bag Life. With Knack, the same 27L laptop office backpack you use as your everyday backpack is also a best-in-class 39L laptop travel packs. Keep your work items in the main compartment and expand the hidden, patent-pending suitcase compartment when you’re ready to take a trip. It’s like two bags (and a Packing Insert + Insulated Water Bottle) for the price of one.
• SUPERB ORGANIZATION: Holds 15.6" laptops. With 3 compartments featuring 12 different pockets, a removable key leash, and numerous card slots and pen loops, everything you carry has its place making Knack the perfect commuter backpack. The expandable/compressible Packing Insert adds additional travel organization and simplicity. Simply pack it before you leave and put it fully packed into a drawer at your destination to live out of it during your trip.
• PEACE OF MIND: The Knack backpack includes theft-proof features such as lockable zipper sliders on all main compartments. With a fleece-lined tablet pocket, padded laptop compartment, and anti-skimming RFID-blocking pocket, Knack Packs protect the things that you value from life's bumps and bruises.
• COMFORTABLE CARRY: Each Knack expandable backpack for men and women is built to make carrying a heavy load as easy and comfortable as possible. Strong, yet lightweight, fabrics and components result in a commuter backpack that weighs less than almost all other similarly-sized backpacks. The ergonomically-designed straps and handles are made with high-quality, closed cell EPE foam and the Comfort-Cool, custom-molded back panel helps reduce heat buildup on your back.
• REASSURING QUALITY: From customized zinc alloy zipper pullers to Duraflex buckles to YKK zippers, Knack Packs use materials that are built to last. We also test our heavy-duty backpacks for men and women against more than 15 globally-recognized standards for things like abrasion resistance, puncture and tear resistance, seam strength, and shoulder strap strength so that your Knack never lets you down.
