Overview The Dia Backpack from Highlander is a versatile, lightweight backpack with plenty of pockets for all your essentials, whether you’re packing for a day in the hills or a walk about town. The main compartment contains a hidden pocket to protect a laptop or tablet and room for a hydration bladder for on-the-go hydration, though we understand why you wouldn’t want to use both at once. A moulded foam back system makes this bag comfortable to carry with you all day, even if you do fill it to the very brim.
