I have a "bug out bag" pack for me and one for my wife.  I find that bagging up gear (particularly tech gear) helps keep them clean and undamaged.  

I have an old impulse/heat sealer.  I use it with those airfilled cushion things that companies use as packing peanuts.  I cut the bag open on the end, drop the radio/batts/wires/whatever in the bag and reseal it.  Tough, translucent, and free.
