Hi Jesse,
I have the A6000 and the 16mm, 16-50mm, 55-210mm lens, plus some other non sony lenses I'll occasionally use with an adapter. I'm not made of money and it would kill me to damage this camera as I can't afford to immediately replace it.
With that being said, I bought this camera to take pictures, not to be a freeloading brick in my backpack. I take what I feel are necessary precautions to protect it but it gets used and has seen more than its fair share of dust and trail miles.
I don't use a camera bag at all. If it's raining, I have a gallon sized ziplock bag that I'll stuff it in to and then pad it with clothing in my backpack. At night, I'll put the camera in the ziplock and leave some air in it so it'll float. I've been guilty of the occasional lazy pitch and have woken to a surprise indoor pool in my shelter.
If it's not raining, my camera is on me and ready to shoot. For most of my backpacking this summer, I carried the camera diagonally across me so it's ready to shoot at a moment's notice. My favorite strap right now is the Peak Design Leash.

With some of the bears I saw at Rainier this summer, if I would have had to dig my camera out of my pack, I would have missed the shot as I only had seconds. I'll caution you to get a screen protector but the camera was fine on multiple backpacking trips that ranged from rainy, dusty, windy, etc.
The PD leash is long enough to raise the camera to your eye when you want to use the view finder. I'm 6'3" with a long torso and the camera carries comfortably on my hip this way. I was at a hockey tournament this weekend and carried the camera diagonally this way with the 55-210mm lens every day.
I've recently added a Peak Design Capture Pro, PD micro plate, and PD wrist strap.

I've only used this system on one hike but I like it and plan on using this system this summer. I leave the cuff on the camera and run my sternum strap through it. The purpose is twofold: a) it protects my camera from a crash if the capture pro fails (it hasn't yet) and, b) I can let my camera hang from the sternum strap if I need to free up both of my hand for some reason when I'm fiddling with the camera. I won't bring both the leash and the capture pro.
I also bought Peak Design's Pad Stabilizer but I don't care to use it with my backpack and don't recommend it for the A6000 on a backpack shoulder strap. It may be fine for carrying a DSLR on a belt but I've yet to carry a camera that way.

I couple other off topic comments about the A6000. I found that I was getting better pictures with the 16mm prime than I was with the 16-50 kit lens. The 16mm was the only lens I carried with me on the Wonderland this year. I don't regret leaving the 55-210 at home but I would have enjoyed having a macro lens. I hope to buy one later this year.
I never use the 16-50mm any more.
I've purchased Wasabi batteries for a couple cameras now including the A6000. I think they're a great battery for the money. I like having a traditional charger when traveling although I charge batteries in the camera on a routine basis, including this weekend when I realized that I left my spare batteries at home and had to top off my single battery between hockey games in the car.
Leave the camera in airplane mode when hiking. Change the settings so the camera doesn't automatically display the picture after you take it.
Tell your buddies to download Sony Play Memories ap to their smartphones before going on a hike. It's a great way to share photos on the drive from the trailhead to the post-hike burger joint celebration.
Again, get the screen protector.
Again, don't baby the camera so much that you don't end up using it. It's not weather proof, it's susceptible to damage, you may indeed damage it, but my experience has been that it's a sturdy camera and is fine to carry at the ready when hiking.
Don't delete the photos on the computer. Once you're done downloading the pictures, format the card in the camera. If it gives you some goofy "battery error" message (only happened to me once), you're having a SD card issue that re-formating the card should remedy.
On that note, always have a spare SD card.
There's more but those are the major ones for me this year.
