All right I will start the constructive bashing (rather like a hammer i'nit?)
Big agnes pad
the prolite 4, 3/4 length may be worth checking out, or rather any 3/4 length inflatable, because you can use the cushy padding on the bag for your feet, and probably when you factor in the fact that you may not even use all of the pad's length if you sleep on your side, for example, a torso pad like the bozeman mountainworks Torsolite could be worth your time, and its almost half the weight and more insulating.
Drop the footprint if your not really camping on something that will pierce the floor. What most folks around here do, instead of the tent, is the tarp + water resistant bivy with bug netting. In terms of logic, this turns a tent into a high space, highly usable "vestibule", for cooking, hanging out, and doing stuff when its really pouring and the bugs are hiding, and has a small bug proof area, and the waterproof floor eliminates the need for a footprint. Good examples of these bivys are from bozeman mountain works, mountain laurel designs, equinox, and a few others, but most of them are pretty similar. If your really cheap, you can make one, like I am planning to, and get a real quality product for cheap, and I think alot of them are ridiculously overpriced. Thruhiker has some good momentum .9 fabric, spinn nylon, and mesh for it, and I know of an awesome design at
Why do you have all these drysacks AND a pack cover?
Cut some of the misc. stuff. TP and trowel are pretty non negotiable for many, but if you look around there are people who learn without. Mike Clelland wrote a hilarious article in techniques about TP substitutes, and sticks, stakes, poles, and trekking poles could sub out the trowel. Hygene wise, often the best set up, is tiny (2-6 fl oz) droppers for alcohol gel and Dr Bronner's, which should cover the needs of hand wash, toothpaste, shampoo, emergency gear washing and so on. Rethink your compass and first aid kit, but thats probably the place where you should not bargain ounces for.
Sub out one of your cutting tools, or do you even need one? I think my next set up will be tiny swisscard scissors and tweezers, and no knife or saw at all.
Water Carrying and treatment wise, take a look at aqua mira, or the bota of boulder outback filter, but the Steripen idea is probably the most bomber and tasty, while aqua mira has a taste and filters dont kill viruses. Drop one of your bottles, I see most people apart from when trekking in desert, carry only 1.5-3 liters, and use smart refilling at water areas, and water adds up weight really quickly.
Buying alot of stuff is expensive, but making your own gear is probably the cheapest way to going really light and still having a heavy wallet. home made tarp, bivy, quilt (these can weigh as little as 12 ounces for a 40* bag!), a pepsi can stove, and a heiniken can pot, along with your clothes and pad, would probably weigh in at around 4-6 lbs, and then you can carry a lighter backpack, or even make your own from many templates available online. Otherwise its $200 for a pack, 200 for a quilt, another 200 for a bivy... and so on.
Im really bored right now, explaining why I've spent so much time on this, but I hope this helps rather than overwhelms you, thats basicly the ultralight+comfort idea in a nutshell.
