My notes and insights...
Frameless Pack - 30.5 oz w/Hefty Bag Liner - Get a lighter backpack, lots of 'em out there, and often they are cheap.
30 Degree Sleeping Bag - 48 oz - - That's heavy. If you wanna keep the porky pad, go with a lighter sleeping bag.
Self Inflating Sleeping Pad - 24.4 oz - - Overkill, but you say you wanna keep it. Just so y'know - You could easily save a full pound with a BPL torso-lite pad.
Tarp w/ Ground Sheet- 16 oz - You have a GIANT pad, so you can nix the ground sheet. You'll be fine.
Titanium Cup - 2.5 oz
24oz Heineken Pot- 1.6 oz
- - - Cup and Pot? No need for both, choose the lightest option.
Clothing in pack: Underwear - 1.5 oz
You can easily nix these. No need for extra underwear, just wear one pair for the duration. You'll be fine.
Towel - 2 oz - No need, easily NIXED, you'll be fine without it.
Toiletries: [ 6.55 oz.] - Wow, 6.55 is a LOT.
Toilet Paper - 2 oz (in ziplock) - Easily nixed, the weight goes to zero if you leave it behind.
Travel Size Gold Bond - 1.5 oz - Easily Nixed, or, repackage in a smaller container. 1.5 oz is too much.
ID, Credit Card, Cash - 0.5 oz - Easily hidden in your vehicle, or near the vehicle. No need to carry in the backcountry.
Cell Phone - 4 oz - I understand the reasons for wanting a cell phone, but it can easily be left behind.
