I typically do the normal 3 season backpacking but i have done a winter trip and my OR Bivy held up well along with my Sawtooth membrane.
Sleeping Bag Liner - I only use this because of the DEET for the bugs so as not to damage my bag.
Camp dishes except 1 small plastic bowl and mug. 4-5 oz max
First aid kit I will probably just use my AMK .3 kit moving forward. the larger kit has a ton in it and my son carries a AMK .5
Filter - Good call I carry Aquamira in my survival kit as well.
Shovel - Good call
Bladder - Good call
Daypack - My six yr old said the same.. ;0)
Water straw - prefer to take it if I'm leaving my other filter......
Knife you have almost 2 pounds of knife - Yeah but there is a lot on that knife that i have used for years. To be honest if I was able to carry nothing else I would keep this. Put my USAF survival training in to play and I could survive with just this stuff on my knife for quite a while.
Pillow: Can you use extra clothes balled up? - yes good call
Clothes: I think I'm only bringing 2 pounds of extra clothes. What all is contained in that 5lbs? - I had a Gortex coat for wind and rain protection, fleece, socks, liners, Gloves, stocking cap, underwear and depending on the length of the trip another pair of convertible pants.
8 oz of paracord? Dyneema ironwire is only 1.2oz for 50ft - Already have a good length around my knife so this is probably unnecessary.
Toothpaste, wipes, and camp soap? Dr. Bronner's acts as all three. - I'm not familiar with this but i will look into it.
A flashlight and a headlamp?
You have listed a first aid kit up top and a mini first aid kit.
Quality 20-30 degree down quilts can be bought for ~150-200 and usually weigh ~18-26 ounces.
One person shelter combinations can be found for ~150 and usually weigh ~10-26 ounces. There are also a few bivys for the same price that weigh under a pound.
I cut my sleeping pad down to only what is needed for my main contact points...it now weighs 3 ounces from 18 and I sleep the same.
Once the weight of your gear comes down, you can also look at replacing the pack. I'd do that last though, because until you cut down, you can't use a lightweight pack for a lot of heavy gear.
Yes any feedback helps as long as i keep an open mind.
Thanks Nicholas & Greg
