Everki s dedication to quality, innovation, versatility and continuous improvement comes through in its products, and the Concept is no exception. One of the company s most feature-rich products to date, it is the culmination of two years of research and development into what customers want and need, and what makes a bag work. If the customer is looking for a cheap bag with a ton of features, there are plenty of options out there. If he or she wants a nice, high-end bag with limited features, there are a few good options. The Concept brings its wearer the best of both worlds. Concept Premium Checkpoint Friendly Laptop BackpackThis bag sports many of the quality features for which Everki has come to be known large zippers, leather handle, durable, water-resistant materials, ergonomic straps and back padding, Checkpoint-Friendly laptop compartment (fits up to 17.3 ), and, of course, attractive design. Along with its laptop compartment, the Concept also features two additional large, zippered compartments, each strategically laid out to maximize space and functionality and outfitted with separate slots and pockets perfect for portable USB devices and other small and medium-sized items. Everki s latest endeavor also marks the debut of its patent-pending corner-guard protection system, which provides added padding to the areas laptop manufacturers have cited as the most frequently damaged. A sturdy hard-shell sunglass/gadget case, embedded discretely into its own zippered pocket, as well as a weight-distributing chest strap, water-repellent ballistic nylon exterior and weather cover, multi-function side pockets, and a slot for Kindle/iPad/tablet PC (in laptop compartment) round out this most recent addition to the catalogue. In addition, as with all Everki products, the Concept is backed by the company s Limited Lifetime Warranty and world-class customer service. Space, organization, quality, style they re all part of the Concept.
