Figured I'd bring this back, since I just recently got to put my overnight pack all back together for the summer time.
I think I got it back to how I want it. List:
-Camelbak (with micropur mp-1 tablets stuffed in with the bladder)
-roll of orange electrical tape
-hat
-change of clothes
-self-inflating sleeping pad
-snacks/food
-basic first aid kit (moleskin, sterile pads, band-aids, tweezers, cold compress)
-Pocket Rocket stove and canister
-MSR pot
-paracord
-toilet paper
-55 gal trash bag/heatsheats blanket
-monocular (which sometimes gets swapped for a camera with zoom capability)
-multitool
-headlamp
-spare batteries
-bandanna
-gloves
-mini-bic
-ferro-rod
-GPS
-map of the trail system
-Gerber brushhook
-my jacket (not pictured)
Weight as pictured is 15lbs (with a full water bladder).
I'll add some more food, maybe a bottle of water just to have a bit more, and it should be good for some nice comfortable back-country camping. Usually I like to do a hike in, camp over night, hike out; but, I have gone longer with more food packed and access to good water.
