Hi, all. I'm new to the board, and to lightweight backpacking. I'm hoping some of you can take a look at my gear list (below) and let me know where I can most affordably drop weight.

This list does not include clothes, which is another area where I would appreciate some advice: What are some good three-season clothing options for backpacking in the Northeast?

One other side note: I am mostly backpacking with my girlfriend and dog. My girlfriend is a strong hiker and is able to haul a good bit of gear, but I am trying to dial in my own kit for future solo adventures.

Anyhow, here goes. Thanks in advance for your help!
