My current gear list as of August 2018:

Of course as any backpacker/hiker knows this is my normal list but as conditions change I change the gear I bring accordingly. Also, I am not saying that any of the gear below is what you need to buy, but it is what I have found that works the best for me after trying out numerous options (and I am always willing to try something new). I have 3 tents and many sleeping bags so I switch those according to weather/season. If I am in a group I gladly share some of the group gear (as in I don't carry it all myself).

Most of the time:

JetBoil (first generation)
MSR Water filter (Sweet water)
Platypus 1 Gallon water bag (for water at camp)
Platypus 2 L bag with hose for the trail
REI insulated mug
High density plastic small shovel and toilet paper
Down REI bag (It used to have quite a few more feathers, as it is 30 years old now)
Cotton/Poly blend sleeping bag liner (even if it is warm I can at least sleep in my liner)
Permaware long spoon ("Long Spah")
Scout UL2 tent (it is lighter than my one person and uses my trekking poles)
Klymit Static V2 Sleeping Pad (Neo Air is too warm/noisy for me lately)
Gregory Baltoro 75 (yeah it is heavy, but it is comfortable even with a heavy load)
Unscented Backwoods Cutter (DEET)
50 feet of colored parachute cord (the bright orange one stands out nicely)
Sunblock (I use a waterproof SPF 30)
Columbia wide brimmed hat (foldable, although I never fold it, I do starch it)
REI Synthetic Pants
REI rain Jacket
hiking socks and liners (actually using toed socks lately with no liners)
Longsleeve synthetic shirt with pit zips and role up sleeves
Lowa Renegade Hiking Boots
Trekking poles, Cascade Mountain Tech (Costco)
REI midweight long underwear top and bottom (for nighttime/cold weather)
Midweight gloves
Fleece balaclava
extra pair of socks
Lightweight down mid layer (even if I don't wear it I need something for a pillow)

2 lighters
waterproof matches
