Take your laptop with you wherever you go with the Aspen Rucksack. This pack is perfect for everyday use for those who are constantly on the go. With the laptop sleeve that's the perfect spot to store your laptop and zippered front pocket to side slip pockets, this pack has all the space you need! Adventures are messy. If your Dakine bag gets dirty they 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.
