Quality: 10/10 (high-quality materials, processing) Size: 8/10 Particularities: Anyone looking for a with boardcatcher and makes do with the 25L has found his backpack. Aside from the specific Alpinist property are top no matter (!), I use it mostly in everyday life. Approaching: It fits a thick A4 folder + pure water bottle 1.5l and breakfast + calculator and odds and ends, of course. With a second folder will then unfortunately nothing, maybe two narrow A4 folders. The top closure does not bother, on the contrary, he is probably better than normal zippers as it is durable. Closing and Öffungsgeschwindigkeit are equal. Please note, for people who want to use the backpack for long stretches in the warm climate, there is due to the Alpine equipment no "perfect" back ventilation, such as in the Tatonka Skill 30 the compromise I had to unfortunately take for boardcatcher.
As I said 5/5 for this backpack Tatonka has once again convinced!
