RE: Backpacking/Bivying in
More recently I' ve started using a Butane Gas stove.
The model I have is a Titanium made by Kovea, it weighs next to nothing and fitted on a small cylinder, I get 4 days cooking. It is quick & easy.
I eat drink & cook out of one utensil, which is a large tin mug.
Freeze dry meals are light and taste good. They only take 10 minutes to prepare. Ideal for when you are spent after a hard days hunting.
I frequently use a Goretex bivvy sack (Sleeping bag cover.) Thermarest 3/4 sleeping pad, and sometimes a light tent fly.
I often use a lightweight 4 seasons sleeping bag. It only has down on one side and you can fit your thermarest into a sleeve on the ground side. (Warm even in the snow.)
Not too many extra clothes, just a dry set of polypropolenes to sleep in.
I try to travel real light and fast. Save the energy/weight for hauling home the meat.
Hope some of this info is useful.
