I've owned an Alpine Swiss backpack for over a decade and although its worn its in perfect shape. Never a problem with zippers, seams or fabric. That being said I bought this pack for a vacation trip to Bali next month. It's the same quality I expected from Alpine Swiss. VERY well made. The only critique I have is that its a little smaller than I hoped. I'm a big guy. 6'4", 235 lbs. so for the average size person this is probably perfect. For us bigger than average people its the same struggle with everything. Cars, clothes, furniture, seats on airplanes, restrooms on airplanes, doorway height.... Things can alway be a little bit bigger and we would have no complaints. If you're looking for quality you found it with Alpine Swiss products.
