2 lights: one Impulse, one e+light. The e+light is clipped to my pack normally, used for hiking. The Impulse is used around camp, except for setting up.
3 pr socks: I have diabetes, soo, my feet are always cold. 1pr is for sleeping, only. 1pr is usually drying. One pair is on.
2 lighters: Both are used and de-adult proofed. I never take a new one. Sometimes the flints wear pretty fast, the valve sticks, I loose the roller,flint,spring when I de-adult proof them...even had a couple that just plain refused to light.
When required, the d@mnable bear ball. That 2pound piece of gear is ALWAYS redundent it seems. (I know out west not so much, but in the ADK's???)
On occasion, I bring a nalgene bottle, but recently I found mine had a leak near the top.
