Bug shelter - Wife wouldn't allow it, lol
Jacket - this is an insulation layer, not an outer shell, so I kinda need it. The E poncho is for the rain.
Filter: What do you mean "pre-mixed"? If it doesn't make the water taste funny, then I'll have to try it out. Generally the water is pretty clear and procured from flowing streams. I've just always been told the drops make the water taste funky, and you have to wait a long time. I'll have to pick some up, see how it goes.
Aquafina bottle - I could, but I like to mix powdered drinks in it for lunch and dinner, it keeps my bladder clean.
Toilet Paper - Use leaves?! I'll let YOU tell that one to my wife... :)
Towel - I suppose I could nix it. It's just nice to take a dip if I'm out for more than an overnight.
Notebook + pen: Ok.
Gorilla tripod: But how would I take pictures like the one in my avatar?!
First Aid: I did get it a little lighter. This also includes a repair kit, and eye drops(I wear and sleep in my contacts), and a few motrin and Pepto.
1.4lbs per person: I'm assuming you're talking about food?
Well, when you posted your list after mine on that other forum, it was kind of a wake up call. And the idea of only carrying 20lbs. or less sounds awesome. Heck my trail patrol pack weighs almost that much with just water, first aid, and some tools!
Re Sleeping bag: I know, I know, I'm a cold sleeper, I'm not sure I could do it. I had a 32* bag once and froze to death. My current bag is actually a 10* bag, and I don't think I've ever been out below freezing. I should maybe try another pad sometime. Currently I fold in in half for a R-4? rating torso pad, and put by pack and extra stuff under my feet. What kind of pads would you recommend if ever I wanted to give something else a try? My pack design relies on the pad as a frame though, so...
I was able whittle down a few of the things I mentioned to get down to a 9.1lb base weight, but for some reason when I upload a new gear list, it doesn't update?
