At 12.8 oz. (363g), the Ultralight Laptop Day Pack from GBY is the lightest laptop backpack in the world with high-density foam shock protection. The Ultralight Laptop Day Pack is designed for the everyday professional who wants to take advantage of the performance characteristics of a featherweight pack. Our day pack is and ultralight computer bag designed for real people — with zippers instead of flaps, clean and simple lines, padded ergonomic straps, and all the small details that provide the most efficient daily wear experience. All of our favorite lightweight outdoor day bags have flimsy and insufficient laptop protection — and generally clumsy entry and retrieval. We love the spirit of ultralight, but we want something we can use everyday during work hours. In response, we combined the impact protection of a heavy duty laptop backpack with the beautiful minimalism of an outdoor ultralight pack. Your $3k laptop will rest safe with our 360HD high-density foam protection. Our foam protection runs the entire length of the backpack with a reinforced bottom. This laptop bag fits all Apple MacBook Pro laptop computers up to 2019/20 16". Access to your important goods is optimized for daily use, not backpacking. Top zip entry is a breeze. We also designed a special outside zip pocket that can be accessed with removal of one strap for quick access at the train or airport. The inside 'mess' pocket is simple to use and easy to find with your hand as you reach in the top of the bag. This inside pocket is perfect for a laptop charger and small notebook. The Ultralight Laptop Day Pack is also extremely water resistant. It starts with our special SS2-Ultra waterproof ripstop nylon, sourced from Japan for it’s smooth hand feel and ultralight strength. All internal seams are reinforced with purpose-selected lightweight binding. What good is waterproof fabric if your zippers are not on the level? We install custom YKK water resistant zippers throughout; the finest available in the world. What good is a great design without the commensurate quality? We stand behind our product. All of our products come with a 1-Year Warranty against construction defects.
