Carry your load in style with the Rucksack featuring a retro outdoor look in a classic top-loading rucksack design. The bag features a dual cinch closure plus a carabineer latch connecting to the woven web daisy chain. Whether you're trekking across campus or across the ridgeline, you'll be able to easily access your goods through the top or the handy side access. Happy trails indeed! 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.
