I have a 7D, a 1740 and a 50 1.8 Guo Xuwei. Because I want to travel, mainly mountaineering, I want to buy a backpack. Please recommend it.

It would be much easier if the budget was 1500. Recommend a brand I like: NG 5 162, National Geographic Earth Explorer Series. The online quotation is: 1299 yuan. Medium-sized backpack, with detachable double-layer structure space and detachable sponge grid in the lower space, can accommodate 1 SLR camera body, 4 lenses, a flash and mobile hard disk, charger, 17-inch notebook and other equipment; The upper space can be used to place travel goods such as clothes. According to your own equipment, you can assemble or disassemble the grid at will and place the equipment. Pockets with different spacing are distributed on the top cover, bottom cover, back and side.

Material: pure natural environment-friendly fiber material, cotton and linen processing fabric, soft texture and good feel. Soft and has excellent air permeability and wear resistance.
