DaKine Atlas Backpack
The Atlas is our go-to backpack when people ask for a school bag that can carry a skateboard. It's not the largest bag at 25litres (the campus holds a whopping 33l!) BUT we can still comfortably fit 4 x A4 folders in the main compartment with room for a lunch box and that's without using the internal 15" laptop sleeve or the front and side pockets! Loadsa room then, plus it has front pocket, side pockets AND a little 'sunglasses' poclet which is simply a soft lined stash pocket at the top by the handle.
Most importantly it can carry a skateboard with Velcro adjusting vertical carry straps. All that for just £40!
-Non padded laptop sleeve fits most 15" laptops
-Skate carry straps
-Fleece lined sunglasses pocket
-Zippered side pockets
