A great buy, widely justify the high price. The design of racks and boxes is very well thought out. The robustness of the whole is flattering. I use it in the workplace and in spite of its large capacity, it does not present itself as a "backpacker backpack" .An important advantage is its compactness; despite a large capacity, the bag does not seem disproportionate when half full. I use it on the road bike with my laptop 17 '' + mouse + charger + iPad + iPhone + iPod + change of clothes + shoes + toiletries ... and it is space.
