The Rucksack is very sturdy and perfect for International travel. I purchased this for my son for his trip to Ireland this summer. It will be able to hold all the items he needs and fit in the carryon compartment. Based on what I saw this rucksack should last forever and one extra day! Both he and I love it.
This backpack/rucksack is the best one I have ever tried . I am in college now and during high school, I went through a backpack every year. This one has a lot of room and the straps are really comfortable.
I think this bag is great in terms of volume and number of pockets but I think there are a few improvements that can be incorporated to make this a better bag. (1) The shoulder straps are thin and a little uncomfortable with heavier loads. I think a little more padding would go a long way. (2) I think the waxing on the cotton is thin and not nearly as impregnated as it should be. This is a detail that I think is important for the bag to be comparable to nylon bags.
