The Ryder backpack with low-profile webbed shoulder straps and a drawcord closure clearly takes its style cues from the laidback beach life. Dakine added the unexpected benefit of a dedicated padded laptop compartment with zippered side access to this otherwise casual-minded bag. Sunny vibes will always follow you around with this fun and functional backpack. Details: Fits most 15'' laptops, side access padded laptop compartment, drawcord closure under flap, adjustable web shoulder straps, interior zippered pocket, padded bottom panel, 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: 1450 cubic inches (24 liters), 17'' x 12'' x 5.5'' (43 x 30 x 14cm). Material: Cotton Canvas.
