Backpack gear
I'm a big guy (6' 3"). Here as some of my favorites, without regard for budget:
MSR Pocket Rocket stove. Great stove...very reasonable. (Basically used to heat water for coffee, instant potatoes, freeze dried dinners, and instant oatmeal)
Trekking poles are a MUST on a backpack hunt, especially when packing out game! I like Leki Makalu Antishock
You might have clothing, but Arteryx Gamma Light pants are out of this world, for weight, durability and stretch! They are spendy though.
Though I have not used one, I have heard rave reviews for Montbell UL Spiral Down Hugger sleeping bags. Due to the design, and how the fabric is laid out on the diagonal, they are supposed to fit bigger guys through the shoulder better. If I buy a new bag, that is what I will be looking at.
Hilleberg makes some of the best backpack tents, but they are not cheap.
I have used a Steripen for water purification and love it. It uses UV for purification, so no flavor of tablets added to your water, but you carry a bit more weight than if using purification tablets.
Snowpeak Titanium is a very nice cook wear set.
Sleeping pad: Thermorest Neoair (Large). Very light and warm.
One thing that has worked well for me is to pack daily rations into 1 gallon Ziploc bags (one day of rations per bag). Pre-packing daily ration bags makes it easy if you come back to the rig and want to restock quickly. Along with your food ration, include a daily ration of TP, Always Wipes-To-Go (2/day for the backside), Wetones (2/day for the hands and face), and three paper towels. Everything should fit in the Ziploc except for a Mountain House freeze dried meal for dinner. Here are some ideas to make your daily meal rations:
Breakfast - Instant oatmeal
Breakfast - Granola type bars (I like honey oat bars)
Breakfast - Carnation vanilla
Snack - Hard Candy
Snack - Trail mix
Snack - Energy bar
Snack - Beef Jerky
Snack - Nuts
Snack - Hot Chocolate
Snack - Crystal Light small to-go packets (for flavor in your water)
Lunch - Smoked clams or oysters
Lunch - Vacuum packed tuna in foil bags (available at grocery)
Lunch - Small mayo packets (for tuna)
Lunch - Candy bar
Dinner - Instant masked potatoes (these are at the grocery in small foil type bags)
Dinner - Mountain House freeze dried dinner (Pasta Primavera and Beef Stroganoff are good)
