The sleek and simple 365 backpack has everything you need and nothing you don't. The roomy main compartment features a non-padded laptop sleeve and the zippered front compartment holds all your smaller items. The 365 is ideal for everyday use thanks to padded shoulder straps and a durable padded bottom panel. If your Dakine 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. Dimensions: 1284 cubic inches (21 liters), 18 x 12 x 8'' (46 x 30 x 20cm). Material: Polyester.
