We use this day pack a lot. It is great for hikes. Very comfortable as it does not touch your back. Multitude of pockets allows you to organize your little stuff. Only drawback that I can see is its rigid frame which doesn't allow much of bulkier items in your pack. However because of it it is very nicely ventilated. Sweaty backs are less likely.
