Roll into class or the office in cool, comfortable style when you have the Dakine Hudson Messenger Bag slung over your shoulder. This quality-constructed messenger bag features an internal padded sleeve for your laptop, enough room for your binders and books, and cleverly-designed organizational compartments for your small essentials. 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: 1200 cubic inches (20 liters), 17'' x 11'' x 5'' (43 x 29 x 13cm). Material: Polyester.
