Hmmmm.....
Where you at?????
I live in the Arctic, and I carry enough to spen the night out, properly dressed, semi comfortably.
At the least you need to add;
A compass, so you know how to get where, as chasing an animal about the woods or in a snowstorm, can get you confused fast. Stay Unlost.
Toilet paper.
A small first aid kit, and some adhesive closure strips, your working with a knife and a gun, both can do you in.
a hooded sweater, they have lots of uses, even as a bag.
extra socks, in a big ziplock,maby extra gloves, if your get wet or bloody.
A gunnysack, to stick all your stuff in if you need to fill the bag with something else, or fill the bag, with organ meats, the skin, ir birds and rabbits, if you dont want the pack itself to get bloody.
At least "Space blankets" They can help you signal as well, if you need help. they tear easily, but you can wrap your feet and put them in the gunny sack if you neeed to dry your socks/boots.
A small honing stone.
550 cord is AWSOME...rope is a tool of thousands of uses.
Lighter fliud, and srtike anywhere matches, in a water proof container. It is VERY hard to start a fire when you are wet and cold, and sticks soaked in gas with a stick match struck into the pile will go off every time.
A tin cup. Scoop out blood, melt ice for water, drink your coffee, or if its severly cold, to add heat to your body from hot water. Being properly hydrated is VERY important, more than food.
That dont weigh much , either. In my bag is so much more, but it rides in the boat, or on the Honda or the snowgo, and is adjusted for the time of year. We call them "Travle bags", and everyone has one up here.
I carry two heater meal MRE's...food, coffee, a pice of sweets, matches and ass wipe, all in a water proof pouch, I highly reccomend them.
Good luck hunting.
