Photo Equipment Cases: cases that can control the internal temperature?

I'm looking for information regarding storage of photo equipment in an automobile for extended periods of time. Many cases I've researched can predict what temperatures the specific case can withstand, however, they don't rate the insulative properties of the case. Any recommendations?Photo Equipment Cases: cases that can control the internal temperature?
Not so much a rec on cases, but you can use those pocket warmers in extreme cold to warm the contents of the case (say up to 8 hours). I know they make cooling packs too.





For best insulation, you might look at food transport cases rather than general photo cases.Photo Equipment Cases: cases that can control the internal temperature?

Just store you equipment in a cooler - they are usually well insulated.
