I had one of those rubber hybrid, air-purge style dry bars, but wow are they heavy! I got a couple sil-nylon compression sacks instead.
I traded up my stainless steel cook pot for a titanium 1 litre pot out of the scratch and dent bin. A great deal and far lighter than the stainless model.
I am looking for a new sleeping bag right now. I currently have one of those MEC hybrid bags. A great dollar value but quite bulky and heavy. I am seriously looking at the Sierra Designs dri-down line. I am also considering a lighter tent. Currently the only tent I own is a Mountain Hardware Trango 2. Bulletproof tent, but a tad heavy, pushing 10 pounds.
Along that same vein I recently upgraded to a neo-air xtherm. I am thinking I can now get away with a minus 7 bag for most early fall hunts until mid to late October moose season anyway.
How do you like the Steri-Pen? I am currently running a Katydyn Vario. Great filter especially for extended hunts, but a little heavy and I have left it at base camp on more than one occasion to bivy out for a few days.
Depending on length of stay, 2 pairs of socks may be a bit light.
Staying under 50 pounds is a goal of mine each year, but I do tend to run heavy of that. When you start with a Mystery Ranch 7500 bag, your handicapping yourself a few pounds right off the bat. I think if I shed a few ounces from my sleep system and clothing, I will get much closer to that goal.
