Now I have only ever had the backpack a few short while, but as far as he is super. As daypack it's great. Everything is well made and all practical little things are hidden that absolutely justify the price. For Example: - Emergency whistle on chest strap is integrated into the buckle - Infinitely adjustable Brustgurthöhe, - Padded inside "thumb-loops" at the end of the Vario system tapes A good wearing comfort is given also definitely and extra ventilation through the Vario system completes the package. As a single defect I honestly would see the bottom compartment that at full bepacktem backpack no longer quite as good rises.
