Newbie - Camera/Lens Case

Hello, I recently bought a Sony 6700 month ago and been loving it, so far I have the sigma 18-50 and the sony 70-350. I having trouble on how to store everything. I go hiking (2-4 hour hikes) with my camera a lot so a camera backpack doesn’t give me enough room for everything else. What can I get to feel not as cluttered? Even when I go out to a park or lake to take pictures it feels like I’m bringing too much with me, my backpack, carrying case for my lens and case for my camera. Or am I just being too overprotective of my equipment?
