The Network II is a professional briefcase in backpack form featuring a clean exterior design. Inside you'll find most built-out backpack featuring multiple accessory pockets for cords, mouse, hard drives: a flip out TSA laptop sleeve, document sleeve, a fleece-lined iPad sleeve, a home for your headphones and much more. The pack keeps its cool with an ergonomic molded foam backpanel and breathable mesh shoulder straps for comfort and enhanced air flow. Like you, this pack easily makes the transition from business meetings to casual Fridays. If your bag gets dirty, Dakine recommend hand washing with mild soap (like Nikwax Tech Wash), cold water and a soft bristle brush. If hand washing is not going to do the trick, use a front loader washing machine. To ensure your backpack doesn't get tangled, place inside a pillowcase or mesh bag before washing. Always use cold water, mild soap and run on a gentle cycle. Never bleach your pack. Hang to dry in a warm but shady place, ensuring both inside and out are dry before storing.
