I'm looking for a new daypack, preferably with an arched, trampoline back, between 20-30l.

Is this Berghaus a good buy for £35 ($44) ? Is Berghaus stuff still good quality, or it's just for fashion now?

Asking you guys, since there are no serious shops here to try bags out in person, unfortunately.
