Alright, maybe this has nothing to do with cycling, but it everthing to do with traveling and maybe some of you could help me out. I'm looking for a rucksack to hold everything I need for a 2-7 day trip. I'm thinking something along the lines of a military rucksack, but I haven't been able to find one that I like. It seems like backpacks these days are either super-expensive internal-framed trekking/hiking/mountaineering packs or small super-expenive school packs and laptop cases. Does anybody know where I can find a rugged, unframed yet sizeable rucksack?
