I bought this backpack to replace / supplement because my old Eastpack (predecessor) to now more 13 years / sports and university system has become somewhat unattractive harsh use in schools. The backpack was claimed really hard and is still fully functional. As part of the 30-year guarantee of Eastpack I had my old backpack again to sew the seams and straps. This quality has convinced me and was the reason that I have enstschieden me again for this model of East Pack.
