Buy European

Yep, got myself a Jääkäri S after getting fed up with backpacks breaking all the time. This time it actually seems like it can stand up to the test of time and lugging two laptops around everywhere.

Whatever the brand, one thing to keep in mind is the material. Nylon (polyamide) can take much more abuse than e.g. polyester. Good if the bag bottom is as continuous as possible instead of being held up by seams. Savotta also adds reinforcement on the bottom so it doesn't wear as much from weight.

If you happen to be in Finland it's Jääkäri S currently on sale in Motonet for 90 € – not sure if they ship elsewhere in Europe though.
