I wrote another review about another very similar Ogio backpack we bought, and I'll say nearly the same thing about this one: while a bit pricey, it's worth it.  Solid, tough, yet sleek, with great compartments.  Fully loaded it feels like it's not stressing the materials or construction at all.  The handle at the top is strong and feels really good.  Our middle-schoolers love their packs -- they are designed well, they look great, and they feel like they'll last through a lot of wear and tear.
