Adventures are messy. If your Dakine bag gets dirty, they 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.
