Hi, I'm a college junior, love backpacking, taken many, many trips throughout the country. In a few days I'm shoving off to New Zealand to study abroad for the semester and realized that it'd probably be best to invest in a pack. I've always used my dads big LL Bean pack (couldn't tell you the model or capacity, I just know that I could live out of it fairly comfortably ((I'm kind of a minimalist, I don't need much)) for up to three weeks, including sleeping bag and pad) but I'm gonna be gone for awhile, and he might need it for himself.
While I think I'm definitely going to actually be doing something hiking and backpacking I might also spend a good chunk of time just backpacking through the country. Any recommendations for the kind of pack I should buy? Maybe even where I should buy it? I'm not really tech saavy, as I've mostly used my dad's gear when it comes to the more expensive items like packs and such.
Thanks for your help.
