The Lunch Box is the perfect size soft-sided cooler ready to transport your cold lunch, snacks or anything else you need to stay cool throughout the day. Carry the cooler by the soft handle and show off the great patterns or drop the Lunch Box into your purse or pack. Adventures are messy. 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. Details: Insulated cooler, interior zippered mesh pocket, limited lifetime warranty. Dimensions: 305 cubic inches (5 liters), 10'' x 7'' x 4'' (25 x 18 x 10cm). Material: Polyester.
