New Sadie cinching pack is a casual bag that's great as a beach bag, day pack, even a small over-nighter. Load up the Sadie and then simply cinch the braided drawstring closed. You can stash your valuables and cell phone in the easy-access side zippered pocket. The wide webbing backpack straps are comfortable and fully adjustable for a tight fit or a laid-back slouchy look. Details: Rope drawstring closure, exterior zippered back pocket, adjustable web shoulder straps, limited lifetime warranty. 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. Dimensions: 920 cubic inches (15 liters), 17'' x 15'' x 8'' (43 x 38 x 20cm). Material: Polyester Woven, Canvas.
