Well, this is confusing the heck out of me. I have no idea of what a 50 litre pack looks like. I plan on getting a back pack from Mountain Equipment Co-op (www.mec.ca I presume)before I leave for Amsterdam, and would like to get an appropriate one. My trip is only going to be 2 weeks, but I also want something I can use to take stuff to university, and something decent for my future summers of bumming around Europe. Oh yeah, Im 6’ 1 too, in case that makes any differnce. Thanks!
