The ultimate surf pack had been updated with all new styling for 2017 sealing its place as the ideal fully waterproof pack. A roll top closure and welded construction make for a total waterproof seal in the roomy main compartment, while PU coated zippers provide water resistance in the dual outside pockets. You'll appreciate clever details like the two-way purge valve for inflation (to make the bag float) or space saving compression, and integrated hands-free board carry system. The breathable back panel, sternum strap and laptop sleeve are the finishing touches for easy-style traveling on your next surf trip or whenever you need total waterproof protection. 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.
