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. This women's lifestyle backpack from Dakine features: Large main compartment, zippered front pocket, vinyl logos and bottom panel, adjustable padded shoulder straps, unlined, limited lifetime warranty. Dimensions: 1500 Cubic incheses (25 liters), 18 x 13 x 7'' (46 x 33 x 18cm). Material: Polyester, Denim Twill, Cotton.
