Hello everyone! I'm planning to take some landscape photos this summer but far from driving road which means I need hike 2 days to reach the location I want. I need to carry 4x5 camera with 4 lens with some accessories, sleep bag, tent, food, clothes. I have a friend is going with me, but he is not going to take any camera equipment. He told me that he can carry tent and some stuffs.

I's told that I need to use a professional hiking backpack instead professional camera backpack to carry camera gears and other stuffs. But all backpack for hiking has no foam protection layer, and fabric of hiking backpack is thin. Please give me some advises on camera gears protection. Thx
