Are you looking for the bag that will help you organise your life? The Nirwana will offer that! The many compartments help you develop a system and if you just need to reach for your ipad, you do not need to open the whole bag. On top of that it is a light bag, so that all the paperwork and laptops are not experienced as ballast. The sides offer a delicate play of colours, so even though the bag offers a serious system, the overall look is one of excitement. The bag itself is made of calf leather, lined with both cotton and pigskin.
