Use this backpack for the university. He really has a lot of space in the large compartment inside. Even the specially separated compartment for the laptop is great, this is especially protected by extra padding and can be transported as safe. A small compartment which from the inside with very soft material is gepolstertvist At the top, perfect for sunglasses or cell phone. Only the 'refrigerator' compartment at the demand side is not ideal. While it is well insulated, so holding was quite cold or I think, but is the more you reinpackt in this subject, the smaller the big compartment inside because the cooling compartment spreads inwards. Not so optimally solved. But since I hardly use this tray, bothers me not. Therefore, 4 stars for a really good, practical backpack with plenty of space and many extras.
