This is the new do-it-all backpack you've been looking for. Built as a quiver of one, this voluminous pack features a top loading design with continuous side zippered access as well as an internal sleeve for hydration or a laptop. The Canyon 28L is packed with tons of features and custom storage including large side pockets, internal zippered pockets, a sternum strap and breathable back panels to keep air flowing and keep you cool whether you're huffing it around town, on the slopes or on the trails. 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.
