I am looking for a backpack for a 1 month trip to New Zealand in January. I am pretty small female, 5-2 but my torso is 17 inches. I am going to be camping, hiking, and staying in hostels, so I will need to be able to fit a tent & sleeping bag. I can pack semi-light, relatively speaking, but I want to be able to pack a few outfits to go out in. I've researched a lot but all the information is so overwhelming... I am also not looking to spend over 200 but if its the right backpack and will last 5 plus years, Ill consider a splurge. Thank you!
