The Dakine Wonder 15L backpack is a low-volume backpack for everyday use or day trips. Everything you need fits into the main 15-liter compartment with a special fleece-lined top pocket for sunglasses. External bungee straps hold extra layers or on-the-go purchases, and there's even a skateboard carry strap on the outer, and room for drink bottles too thanks to the outer pockets. A great little backpack.
