I want to buy a camera backpack with two compartments. The lower compartment is for cameras while the upper one is for clothes, food, water, etc. I saw a model by Sorak. It's cheaper than Lowepro. Is Sorak good enough to use? I'm anxious about the waterproof property of the cloth textile.
Where can I buy such backpacks (Sorak, Lowepro, or others) at a lower price?
