-Surgical tubing: For starting a fire. Air is a underrated tool towards getting some embers going. A surgical tube under your kindling can be used to get air to the most important part of the young fire.
-Barometer: Provided you know how to use it, you can get fairly accurate weather forecasting without a cell or radio signal. Decent battery powered barometers can be found for under $40 now.
-Radio: My favorite radio is a hand crank flashlight/battery combo. I still use my headlamp and keep a backup mini light. The radio is nice should you need a forecast or want to listen to something.
-Solar battery/charger: I've got a nice unit that is a 2x3 solar panel with a built in 8 amp battery pack. I use it to charge batteries, as well as the occasional dead phone. It's about a pound, but a good way to keep me from lugging a ton of extra batteries on a long trip.
