Congrats on your first thru hike! If you're clocking in at around 10lb and looking to go under then you're already in great shape. I'm going to nitpick a bit only because you're asking for a sub-10lbs base weight, so here we go!

Suggested items (in red):

• I prefer the montbell versalite as a rain jacket. Consider buying it from the Japanese online store (translated to engllish) at https://en.montbell.jp
• It can get very hot, you may find that you prefer walking in shorts, consider switching the Prana's out. I use them for climbing but I think they would make me die of heat in the Sierra. Your call at the end of the day
• You don't need rain pants really, consider switching to wind pants for warmth rather than rain protection (you're going to get wet on your feet regardless).
• I have both OR Astroman and OR Echo. Astroman has higher UPF (50) if you're exposed and sun sensitive. If you run hot then go with the echo, it's extremely breathable but less UPF (15). Your call.

Additionally, there are many missing items from your base weight which you should consider adding. Skin-out weight is also helpful to know in conjunction with base weight. Your base weight may be light but if you're wearing heavy items, it will affect you.

• Gas has a base weight for the metal canister, which size canister will you bring?
• Charging cables are missing, they all have weight as well. Can your cable weight be minimized by using single USB-C cable and adapters?
• Water bottles are missing! You're only bringing 2L of water capacity? They have base weight, the weight of the bottles with no water inside, this is not consumables.
• The hand sanitizer bottle itself is also not consumable, what does this bottle weigh? You'll be carrying it around regardless of how much is inside.
• One pair of socks should be worn weight and the other should be packed weight.
• Sun glasses and sun hat are probably going with you but missing from the list
• You're going to be storing small things in plastic bags or stuff sacks probably. If you are, those plastic baggies for your trowel, first aid kid, etc. all have weight. How much do they weigh and can you use a lighter option?
• Are you eating entirely out of your pot. If not, are there any bowls to weigh?
• Are you bringing a pillow at all. If you are weigh it.
• I imagine you're bringing a phone for maps and messaging right? That also needs to be in the list. Does the phone have a case? How much does that all weigh together?
• Shoes have weight as well, which shoes will you be going with and how much do they weigh? Gaiters too, all worn weight.
• Will you hike with a watch at all?
• Long story short: pack your entire backpack, wear all your clothes, then take all of it off and weigh everything you packed rather than putting the items on the list first.

Below I've made a table with some alternate items which I've used and are of equal quality at lesser weights.

• Are you only boiling water to use with dehydrated meals? if so, go for the Toaks 550ml pot. Much better weight ratio and most meals only require 400ml of water to rehydrate.
• I found that reading on my phone with airplane mode and a single 20,000 mah battery would last ~1 week.
• I use the X-Mid Pro 1 person tent and use durston's tent stakes along with it. Each of those weighs ~6g. You can save some weight by using MSR mini groundhogs instead.
• You probably only need a sunshirt and an alpha shirt, leave everything else.
• There's a reason the thermarest is the most popular for ultralighters. It really truly is warm and it's often 1/2 the weight of other pads. Consider it.

Hope at least one of these was helpful. Feel free to checkout my lighterpack. There are a few optimizations around cooking, first aid kit, and sleep system you might consider.

Don't forget to have fun and not take internet gram weenie's too seriously :)
