NWT Dakine Palm Print Lunch Box 5L The Lunch Box is the perfect size soft-sided cooler ready to transport your cold lunch or snacks on its own or drop it right into your pack. Insulated cooler pocket 310 cubic inches [ 5L ] 10 x 7 x 4"" [ 25 x 18 x 10cm ] If your Dakine bag gets dirty, we 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.
