The only camping is on the inca trail, and you get a sherpa that carries all the tents and equipment. The bag does have a sleeping bag attachment at the bottom and has lots of loupes you can attach carabiners to and hang things like shoes etc.
The trip is a group trip of 12-15 people and mostly hostel accommodation.
Well the camera equipment will be in one bag, the day pack mostly apart from hiking. Leaving the 45l completely free for everything else which will be left at the hostels so I don't have to carry it. I will then swap out items depending on the needs for each days itinerary. The compartments in the 45l are removable too and fold flat and can be used as a full sized hiking bag. It is designed as a camping bag so you can attach your tent and sleeping bag at the bottom. 45l is more than enough room I am taking a multitude of clothing, my walking gear is all designed to be layered up, so I have base layers, mid layers flees and rain coat. Means instead of a big coat you can either add layers or reduce depending to your temperature, similar to skiing.
A lot of my walking tshirts are breathable and are very thin and compact meaning they take up no room so taking 5 of these, mid layers are made from wool so clean themselves so I'm only taking two, fantastic things. I then have a zip flees. Then I'm taking a pair of walking trousers which zip off at the knee for shorts. I am taking casual stuff too, two paris of shorts a pair of jeans and 3-4 t shirts and a hoody. 2 pairs of shoes one walking waterproof trainer sort of hybrid to keep weight down but keep my feet dry and a pair of casual shoes. 10 pairs of underpants and 6 pairs of sock and 2 sets of walking socks.
Then I have medical and toiletries bag. All will be in packing cubes so can be condensed and so I can figure out which one is which. But I have all of this down to a fine art, no liquids apart from toothpaste, solid shampoo to cut down weight and lasts 50 days. I will wash my clothes on the way as there are lots of stops its also cheap, so can keep things down to a minimum.
There is a good post about it below if you want to read more about traveling packing tips. This girl runs her business by traveling and carries a lot more than I am, she is also is much smaller!! Im a pretty well built nearly 6ft guy and she's about 5ft5 and half my weight. But she is a lady so taking a lot of things maybe us boys wouldn't need
The laptop I understand the concerns, but if you are going away for a week to a month I would say fair enough, because you can sort them out when you get back. But if you are traveling for an extend period of time like me you start to miss the use of your own things, using a internet cafe might be fine but means you can't do it when you want. Also I think I will probably get through at least 5000 images in the SA trip, that narrows down to only taking 100 pics a day… as the trip is 51 days and organising 5000 in one go will be a horrendous experience. Hostels all have wifi access whether its good or not is another question. Enough to post a picture and blog post I would say.
I am meeting my parents in LA tho so I could do the 2 months without the laptop and get them to bring it with them, would save some weight. I just like to review my images properly especially when some of these places will have miraculous scenery.
