I bought the pack because of the low price for everyday use and several times mercilessly with purchases packed (Isch Abbe no car!). The backpack wears through the back frame very pleasant, the weight can be felt almost. The length is for me (unfortunately only 1.65 m tall) just right, I prefer to lug around, no mountains with me. The durability in continuous operation remains to be seen, so far, I am certainly very pleased with the good pieces. Update: After more than a year with heavy purchases and books no appreciable wear and tear.
