The UAG (Urban Armor Gear) Composite case gives lightweight military-grade protection for your Microsoft Surface Book. This detachable case features a hard armor shell and integrated shock absorbing bumpers, all guarding against scratches and drops. A rubberized screen surround ensures your device is protected when it’s laid flat on the table, screen side first. This protective lip also provides great grip, so you can comfortably hold your Surface Book while reading or web browsing. The design features a three dimensional vent backing which allows air to circulate so your Surface Book won`t get uncomfortably hot during extended use.
