Reddit reviews Rothco Orienteering Ranger Type Compass

Yep, missed the first aid stuff under hygiene. Looking at the list again I'd recommend Benadryl.

The ranger station for the places you're going through will have maps. If you haven't already you should call them up before your trip anyways to learn about what's been going on lately... lots of bear activity, rock slides, water contamination, or any other seasonal/temporary hazards.

A compass might be "heavy" but there's so many ways your phone can become unusable, I wouldn't recommend relying on it. I'd suggest you consider your phone to be the heavy item and ditch it if anything. Plus, you can get something like this which doubles as both your compass and your signaling mirror, which now that I check is missing from your list. Alternatively this one only weighs one ounce but lacks the mirror. On the trails I hike I can honestly get away with a button compass because civilization is never that far away. In most cases if I can head towards a direction within 10-15 degrees of accuracy I will be just fine.

A full mess kit is a bit much to bring solo backpacking.

My cookware is limited to my MSR pocket rocket (w/ 8oz canister), a simple 12oz stainless steel cooking pot with collapsing handles, a plastic 8oz cup, and a plastic spork. All food I bring in is prepared by following the same procedure: water in pot, heat until boil, pour into food, seal, wait, eat, clean. Preparing meals ahead of time (like your Mountain House there) is key. Breakfast is usually some oatmeal with dried fruit, cinnamon, and brown sugar in a zip lock. Poor water in, let it sit, and eat.

Simplicity is key. A full mess kit is a) extra weight, b) lots to clean, and c) more than you'll likely need unless you're actually going to catch and eat a fish. Even then, bring some foil, wrap the fish and throw it on some coals to cook instead of using a pan.

Edit: there's lots of room for improvement - the mess kit was just what stood out for me, because I brought that exact same one on my first trip years ago, and never used a piece of it after the first night.

Some other "cut" items:

• get rid of the machete; whether you're used to it or not, it's overkill unless you're hiking untamed wilderness or bushwhacking (and even then, if you're practicing LNT you shouldn't be destroying foliage anyway). Also the folding saw can probably go. I've build hundreds of fires and never used a saw to do it. If the log is too big for your fire pit, you can hang the middle of it over the fire, let it burn through, break it in half, rinse repeat. The multi-tool can stay, though they tend to be heavy they are also useful and have more than one use.
  
  
• First aid: all you need for first aid are some bandaids, superglue, a clean "wrap" of some kind, and carry duct tape. Bring a small number of pain pills (acetaminophen and ibuprofen) and whatever other meds you need for allergies. If you hurt yourself to the point that you need sutures, clean and glue the wound shut, slap duct tape on it, and GTFO. I also carry Vaseline for blisters, but I don't bring a jar of it. Instead, I cover about a dozen cotten balls in the stuff and keep them sealed in a baggie. This has a dual purpose, the first and most obvious being first aid, but the second being fire starting. The cotton acts as a wick while the Vaseline burns, and it keeps a nice little pilot light going for you to add tinder and sticks to. The way I make them, they burn for a solid 5 minutes even in moderate wind, so they are IDEAL for starting camp fires.
  
  
• Engineer's compass is overkill. If you're using a map and compass to navigate, you'll want a lighter compass like this one. Lighter, and more useful for triangulating your position - but takes some practice to learn.
  
  
• Any liquids you're bringing, like that camp soap, should be pared down into smaller travel bottles. Don't bring the whole thing. You won't need that much, and it's added weight.
  
  The bottom line is you're going to get out there with 40 lbs worth of "stuff" and realize you didn't need a lot of it. It's easy to see a huge first aid kit and start thinking you're going to need 5 different types of gauze pad, but the reality is you'll be much happier leaving stuff behind. Only experience can tell you what you should have left at home. Once you get back, take notes on what you used, and for what purpose. If something doesn't make that list, or if something only has one use, it can be left out next time.
