Take on a day full of classes with room for everything you need. This is the new do-it-all backpack you've been looking for. Details: Padded laptop sleeve, fits most 14'' laptops, organizer pocket, mesh side pockets, fleece lined sunglass pocket, adjustable sternum strap, limited lifetime warranty. 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.
