Scratch all of that.
Get bagged freeze-dried meals (like Mountain House but there are others), shell out a few extra bucks for a titanium 500-750ml pot, get a cheap stove like this one, and a small canister of iso-pro fuel. Cop a titanium/aluminum long spoon and and water in bottles or a hydration bladder and you're set. Keep the kitchen at your bug out location. You're just trying to travel light as possible to get to your main camp or location as quickly as possible where you'll have all the main stuff.
All good recommendations.
Amazon links for recommended items:
The Osprey Atmos is a more popular backpack than that Volt. Fit is really the most important part of this - so if you have a chance to try either on - that would be ideal.
These poles are better than the ones you have listed:
The North Face Venture jacket is more popular / recommended than the Resolve:
Skip the solar charger. A USB battery pack is way more useful. Solar are just too bulky and low charge for the effort. Get 2 if you really need the power.
Tent is really small and not a popular/quality brand. How much time will you spend sleeping in this? Every night? Have you ever slept in a 1-person bivy style shelter before? Where will your backpack go at night? I would not recommend this. If you really need to go this cheap (under $100 is SUPER low for a quality ultralight backpacking tent) - then consider Nature Hike brand. They are a knockoff Chineese company that's somewhat good.
That sleeping bag is garbage. It's super bulky and not very warm. The 32F rating is a straight up lie.
I recommend this bag instead:
You also need a sleeping pad. Not optional. Check this out:
100% skip that hammer multitool. WOW is that thing bad. If you need a knife - buy a knife. You do not need a hammer for backpacking.
The headlamp is great, good choice.
The stove / pot / cook kit is okay. It's a popular budget option. If you could spend a bit more there are better choices. For example:
Don't forget TP/wipes (and a way to pack them out once used), good wool socks, dry bags / pack cover, food bag, water bottles, map, first aid, toiletries, lighter, duct tape, phone/camera, and other random items. Plus clothes of course - lots of layers!
Assuming you are reheating backpacking meals; tokes 750 and a DYI alcohol stove
Big 4 for $502
The rest of the gear is relatively cheap, like:
Random stuff from your house / DIY:
Clothes could be a whole post of their own. Start with what you already own and upgrade to wool/synthetics over time.
Food from the grocery store is cheap. Skip the fancy freeze dried stuff. Shout out /r/trailmeals.
Skipping unnecessary items is the best way to save money. Amazon will make you think that a huge knife, lantern, chair, axesaw, and other 'camping' gear is important. Don't let them trick you into wasting money / weight on garbage.
