As a budget hiker the cheapest option to bring your pack weight down is to nix some excessive gear from your pack. Leaving items at home costs nothing.
— nix one lightweight top and one lightweight bottoms and save 8.6oz
— You have listed your Columbia jacket as both an item worn and item carried. As an aside it is also triple the weight of other options out there.
— Three pair of socks and two sock liners. Nix the wool sleeping socks and use a pair of ankle socks. Save 2oz.
– Nix mini deodorant (seriously), save 1.3oz
– 4oz of bug spray– this seems like a lot– repackage into a 1oz dropper bottle ($1.20 from REI)– same goes for the sunscreen.
– GoGirl Urinal, Honestly– 10oz!!! Oh dear.
– You have 9.3 oz of sanitation! Camp soap, wet wipes and hand sanitizer– nix two and repackage. Save 8oz+.
– Nix the camp towel, use your bandana. Save 1.5oz
– You could also nix the Pocket Rocket and get an alcohol stove and save 2oz or so.
– Open Country 2 Quart Pot. A 2 Quart pot is a whole lot of pot for solo use and at 12oz it is heavy. Look at Anti-Gravity Gears 3-cup ($10) or 2 quart pot ($13) and save 6oz+
– Nix the extra batteries and just use brand new batteries for your headlamp. Save 3.5oz
– Cell phone, optional. I would leave in the car because battery won't last more than a day or two. Not sure on the signal on the AT. Save 4oz
– Nix the Spot. You are on a trail!
– Nix the paper towel. Use your bandana. Save 1.2oz
– You also mention a bear bag rope, but no bear bag??
Just by nixing the items with weight mentioned you can save around 3LB from your gear and it costs you less than $20.
