Pack Packing 2.0 — Roots, Game, and Trail

Sleeping bag, waterproofed! (choose temperature and filling based on location, conditions, and your tolerance for sleeping cold)
Sleeping pad (waterproofed)
Tent body, fly, poles, stakes (I’m using a lightweight 3-season, 2-person tent. If you want to go even lighter, options like MegaMid can give you the freedom to ditch the body and the tent poles while staying cozy, weather and bugs permitting.)

Stove (MSR Pocket Rocket is super lightweight and compact.)
Fuel (Iso-Pro all-season fuel blend. If you’re planning on temps consistently below about 20*F, I recommend a white gas stove like a MSR Whisper Light. “All-season” Iso-Pro can be taken with a grain of salt.)
Pot with lid and pot grips
Lighter (waterproofed in bag. I keep a spare in my jacket pocket.)
Spoon (cut the end off to fit in the bowl)
Nalgene bowl (liquid-tight in case you want to save last night’s pasta sauce as a trail snack)
Small pocket knife

All food waterproofed (plastic bags work)
(These food bags can become your trash bags. Pack it in, pack it out.)
If you’re hiking in bear country, you might want to bring a rope to hang your food, or pack your food into a mini bear barrel.)

To hike, I generally wear base-layer top and bottom, sometimes with mid-layer top or hiking pants over them.
I pack extra base-layer shirt and warm mid-layer pants
Change of underwear and hiking socks
Sacred sleeping socks (Starting night one, these socks will migrate into my sleeping bag where I’ll only wear them to bed, keeping them dry and clean all trip, and keeping my feet dry, clean, and warm each night.)
Thin, windproof gloves
Hat or buff for head and a neck buff (multi-use)
Rain pants and rain jacket
Hiking boots (on my feet!)
I might bring a lightweight pair of camp shoes too (like Crocs or runners) depending on where I’m headed and what my goals are for the trip

I usually take 1 or 2 one-liter hard Nalgene bottles. (Water carrying capacity depends on where you are hiking. In the desert, you might want a carrying capacity of more like 4L, in case water sources are few and far between.)
(If you’re bringing a water bladder: Congratulations, you are most likely watering the world much more clearly and copiously than I am. Unfortunately, water bladders don’t always withstand the chaffing of packlife, so it’s important to carry at least one rigid bottle as well.)
Water treatment tablets. (I use Aquamira drops or Iodine tablets. Water filters can be great! Unfortunately, they do break (and often crack in freezing temps) so it’s usually a good idea to bring an indestructible backup treatment system like tablets or drops…. Which, to the lightweight packer, begs the question: Why bring the water filter in the first place??)

Athletic tape, duct tape, Tenacious tape, seam sealer
Ibuprofen, Acetaminophen, Benadryl
Spare batteries (for headlamp)
Ace bandage, gauze, Mole-Skin, and anti-biotic ointment
SPOT or PLB (or cell phone, of course! Good to have some way of making emergency contact if things get messy.)
(Tape, gauze, and anything else you’re carrying in your pack can be used to improvise a lot of bulky single-purpose medical supplies.)
