Peak Design Unisex 30 L Travel Backpack Backpack (pack of 1)

Q: What is on the inside. The images dont show this. I am looking for a large capacity waterproof/resistant bag.

There are some helpful videos that show this and how people pack the bag on You Tube. Just Google the bag name and you will find them. After watching them I decided to buy the bag as there is a large open space inside as well as zipped sections. I didnt bother with the packing cubes that some people use. I havent tested it in a downpour.
